The next day, they all woke up after nine a.m. It had been a rough night and they were all sore from last night's events, but happy to be alive.

Raph's shell was sore as he thought it would be. More sore than usual from even how he would be after training.

Randall's back was more sore than it was last night. His skin had darkened to where he had been hit into the wall. Some bruising had shown clear through, and he had begun to get a stuffy nose.

The others had also suffered some big bruising as well. Splinter also had injection site pain from his arms.

When April came out of her room and saw everyone up, but she saw how there were painful moments that she got some ice packs out of the freezer and the heating pad. They needed some of this.

April gave Randall an ice pack for his back. When he put it on, it did send a little shiver down his spine, it was so cold, but it might relieve some of the pain. And she gave him some cold medicine to hopefully stop the cold from getting worse.

"You don't have to work today if you don't think you can." April said.

"It's just a little bruising and a minor cold. It's not like I broke my back. I can still work." Randall said.

"Alright, but if you need to stop, just let me know." She said.

"Yeah."

"Do you guys think you can go home or do you need to stay longer?"

"We'll stay for today, Miss O'Neil. We'll go home tonight." Splinter said.

"I'm just glad none of you are hurt worse."

"So are we, April." Don said.

"Well, if you need me for anything, I'll be downstairs. There's food in the pantry and freezer, whatever you want for breakfast." April said and went down to open up the shop.

She grabbed a granola bar for her breakfast.

Mikey went to the kitchen to make some eggs, toast and pancakes. Randall joined him. He still wanted to cook at times.

Mikey was glad to have his friend cooking with him. He made the eggs while Randall did the pancakes.

Randall already knew that Mike was best at making scrambled eggs. But he saw why too. He was using the wrong sort of tool for turning eggs over. He also made the toast, as not everyone loved black toast.

April and the others did actually like Randall's cooking. He knew his limits to not burn stuff.

It turned into a good breakfast, and April couldn't help herself to come upstairs and share it with her friends. It had smelled so good.

Afterwards, April, Randall, and the turtles all went down to the shop. They all helped her throughout the day this time while letting their father rest upstairs.

Randall found that while lifting some boxes, his back did bother him a bit.

Don noticed him wincing.

"Are you okay, Randall?"

"Just my back."

"I can take a look at it for you." Don offered.

"I'll be fine." The lizard said.

But in the end, when his shift was over, when April released him for the day, they went upstairs and with Splinter now in the chair, and the other turtles standing or sitting at the table, Randall was lying on the couch and Don was examining Randall's back.

Randall had been a bit thin when he had come to New York, but since living with the turtles, with all that fine cooking over the last few months, he had gained some weight to where his spine wasn't showing anymore. But the blow to his back from the wall had been a good one.

Don was feeling and just massaging his back, trying to get him to relax the muscles, but the bruised area was painful. It was right in the area where his back would bend to allow him to stand upright, right in the middle, where his stomach was in the front.

Randall groaned and winced as Don touched the area.

"I don't think there was any significant damage to your spine, but you did take a good hard blow to the wall from that explosion." Don said when he was finished. "It'll heal in a few days."

Randall had kept his head down so Don could do a full exam on his back. He then raised his head. He realized that the massage had felt good on his back, but not so much on the area that hurt.

"Just put some ice on your back a couple times a day and that should help it too." Don advised.

"Thanks."

That evening, the turtles and Splinter went back to their lair. April drove them to their truck where it had been close to Leatherhead's home and then they drove themselves home to the warehouse and then down to the lair.

Randall didn't go with them. He went down to his basement home. He just wanted to rest. But it had been nice to spend the day with his friends and after helping Splinter last night, he hoped Splinter had some restored trust in him.

At the lair, the turtles went about their own activities. There would be no patrols for a few nights after what happened. They just wanted to feel connected again.

When Leo went to his father before he went to bed, he had to ask, "Father, how do you feel about Randall after what happened last night?"

"Last night proved to me that he is trustworthy, my son. He did try to get me out of there and he helped me to defeat Bishop." Splinter said.

Leo was really beginning to believe it. Randall had helped his father, him, Raph, and Mikey. And Don with his inventions and upgrades.

So Randall had gained some trust back after the ordeal with Bishop. He was lucky that Bishop hadn't seen him, or had he? Or the man would want him too later on.

Bishop was not an opponent to take lightly, like the Shredder and his Foot ninjas. Splinter was otherwise the only one of them that could match his fighting skills. But Randall had showed some potential helping him while invisible.

Randall's biggest advantage to his fighting skills was his invisibility. Not everyone knew how to fight what they couldn't see. And Leo was the only one who had been able to do the detection game with him and sensed right most of the time.

When they were all well again, during a session of training, Leo did want Randall to try his invisibility stealth on his brothers too.

….

A couple of weeks later, on a night when Randall came over to hang out, while Casey was with April, and Randall's back and cold were all healed, Leo told everyone that they needed a training session, including Randall.

"Do we have to, Leo?" Mikey whined.

"Yes, you have to, Mikey. I've already done this exercise, but you three should try it too. As Master Splinter sometimes tests us on this, this time, I'm advising it." Leo said.

"What's this session based on?" Randall asked.

"You remember when you tried your invisibility sensing with me?"

"Yes."

"This time, you are doing it on them." Leo said. "You need to learn to handle more than one person too, Randall."

Randall usually fought one person at a time.

"We'll do the sensing one at a time first, and then we'll do it as a group." Leo said. "Raph, you're up first."

"Is he going to be blindfolded too?" Raph asked.

"No. You guys just turn your masks around. You are going to try to sense where he is, but there will be no weapons used." Leo said.

Raph was wanting to try this. Though he wasn't always crazy about doing it while he couldn't see.

Splinter was watching from a distance. He wanted to see if his sons could do this.

Raph put his sais down to make sure he didn't use them. He stood in the middle of the dojo part of the lair and turned his mask around.

Don, Randall, and Mikey and Leo watched him. He was ready.

"Okay, whenever you're ready, Randall." Leo said.

Randall gave a mischievous grin. He instantly vanished.

The others saw that Leo was serious about this. So Randall was even really going invisible on them.

"See if you can find me." Randall said from below Raph.

Raph jerked behind himself and the lizard sounded like he was behind him, but he moved quick. He nearly stumbled. Randall chuckled.

It wasn't easy for Raph to find Randall as easily as Leo did.

"Come on, Lizard. I'll catch you!"

"Oh really?" He said to the left.

Raph hit out his left hand and nearly got him, but missed again.

After ten minutes of trying, Randall finally struck Raph in the back of the legs and the turtle was down, miffed off.

Raph growled.

"Alright, that's enough." Leo said. He had seen enough.

Randall was good at stealth. He reappeared just as Raph moved his mask back around.

"Don, you're next." Leo said.

Don and Raph switched spots. Raph gave Randall a light shoulder punch when he could finally see him again.

"You're such a showoff, Lizard." Raph said, but he smiled at him.

"I know. This is where I specialize in defense." Randall replied.

"It's fine for you to show off, Randall, here at home, but out there, don't get over confident. There will be some out there like me that might sense you even while invisible." Leo said. "But this exercise is also to help you guys out against possible Foot Tech ninjas as well."

"Yeah, since they can disappear too, and we can't see them without special heat goggles." Don said.

"We should see if we can see Randall that way too." Mikey said.

"I don't know about that. I'm not really warm blooded like a human." Randall said.

"We could still try it." Don said.

"Alright, but wait until after Mikey's turn." Leo said.

Raph definitely wanted to try the goggles. But would Randall show up on heat sensing goggles?

Don tried his best, but he couldn't find Randall either. Then it was Mikey's turn.

Mikey also failed the test.

"Let's see you do it, Leo." Mike said.

"Alright." Leo said.

Randall tried all his tricks with side, front and behind him, but Leo was the only one who could sense where Randall was. Even while invisible.

The three others didn't know how Leo did that. Randall was good at sneaking on everyone. But now, it was a change time.

They all got Don's heat goggles on and tried to find Randall that way.

Randall felt like this was cheating, but he dealt with it. He knew they just wanted to find him more easily for a change.

Randall's body temperature did the same as the turtles really. He was still warm enough to be active. He had warmed himself some during the day.

He had to warm himself every day from the sun. Or heat lights in the basement. The turtles had their own heat lamps.

With the goggles' help, they all could find Randall more easily this time, but more of his movements they were able to see. He still appeared cold to the goggles.

Each turtle gave a little touch to small hit on his body when they saw he was close enough. Nothing bad enough for serious injury.

"You know that was cheating." Randall said when they all finished with the goggles.

"Yeah, but we all just wanted to find you for once, instead of just Leo." Don said.

"Okay, put the goggles away. Now it's time we do it as a group." Leo said.

"Are we turning our masks again?" Mikey asked.

"No. This time, he goes invisible, but we are still going to try to find him and if he does anything, he can. He has to learn to fight multiple people sometime." Leo said. "But Randall, if you were ever in a situation where climbing was out of place, and you had to stay around enemies, we need you to stay around us this time. No climbing the pillars. That's what this session is also about."

"I can do that."

"Alright, everyone ready?" Leo asked.

"Yes." They all said and got into stances.

"Whenever you're ready, Randall." Leo said.

Randall sighed and then vanished.

Each turtle tried going in to find him and they each missed, and Randall would do a little trick of his own. He would slap his hands on their shoulders, heads, jump on them, or trip them up.

Leo did locate him a few times, but even he too missed the lizard and got tripped up and hit by him.

Randall was liking this test a bit. He didn't like being hit, but he was giving more hits than getting them. It was not to hurt him anyway, just a game, but one that could really help him one of these days.

Leo was serious about this training, but some of it did need to be a game too. Just to keep it entertaining.

Don and Mikey were having a hard time tagging Randall, and Raph just wanted to get a hold of him.

When Leo finally did call it off, Randall reappeared and Raph grabbed him from behind, but slightly to his left.

Randall growled. "Let go of me!"

Raph had him by the top arms. "Gotcha!" He said in a playful tone.

"Oh, really?" Randall said sarcastically.

Raph's smile faded when Randall pushed his head back into his face and raised himself up on his very hind legs, getting the turtle to release his arms.

Raph backed off, holding his nose. Then he felt his legs being forced out from under him.

Randall had used his tail to trip him. It was one thing he was known for. He did use his tail as a weapon a lot.

Raph cried out when the wind was knocked out of him when he hit the floor.

"That's enough, Randall." Leo said.

Mike and Don couldn't help but laugh.

Raph couldn't help but growl himself. He hated being a loser in a fight, even a mock fight.

"Raphael, you need to control your temper. This is the way he is." Leo said.

"I know. I just wanted to catch him for a change." Raph said.

"Ain't gonna happen so easily, turtle boy." Randall said playfully.

"One of these days." Raph said.

Raph was trying to control himself. He had tried to see this as a game as well as training. There were times when he did compose himself rather calm too and not lose his cool.

He didn't like being made fun of, but neither did Randall. But Randall had seen it more as a game when he outsmarted the turtles quite a bit in training, but he knew it had a serious purpose. He just had a bigger advantage with the invisibility and natural climbing abilities. Randall was a good adversary.

After that, Leo allowed his brothers and Randall to go do their activities again. He had just felt this session had needed to happen. And it would be practiced every so often to keep their skills up at it, should they ever go up like against Foot Tech ninjas, which they would at times.

And now that the worst was past them, Splinter was glad to see that things were improving in relationships again.

Randall hung out with Mikey for the rest of the evening.

Made it the halfway point!
