It was two days of searching the sewers before they finally found a place that somewhat resembled Leatherhead's home. It was an abandoned subway station.

They were all impressed by the size of it. They all split up to go explore it.

Don knew that the biggest room would be needed for his lab.

When they all went upstairs, each turtle selected a room of their own. And there were a few rooms downstairs that could be used for guests. Until Splinter was here to pick a room, they had no idea what room he would pick, but more than likely, one where he would have more privacy.

Each of the guys had picked their rooms right next to the other. Leo had picked the kids' room that was to the left of his. Don's room was on the right side of Leo's.

Though the kids would have their own room together, while they were very young, when they got older they would have separate rooms. But right now, Leo most of all, didn't want to be very far from them.

At the main exit/entrance to the lair, which was up a flight of stairs, they did some exploring topside to find out where in New York this lair was.

As it turned out, it was more in the downtown of the Brooklyn area of New York. It was much further away than the other two lairs.

After they all regrouped, it was decided that they would live here. Now, they just needed to go back and get Splinter, Hannah, and Brian. Then they would worry about moving in, or they would do the heavy moving first, then bring the twins over, but Splinter did need to see the place that was chosen.

That night, they camped in the new lair to get the new live in feel of the place. Raph went topside and made the phone call to tell April that they had found their new place to live. He asked if they could come and pick them up in the morning in the back alley.

The next day, Casey followed the directions to that section of the city, and though it was daylight hours, the turtles all came out of hiding to pile into the van. Leo was more than eager to be reunited with the twins, as were Don and Mikey.

It was quite a long drive back to April and Casey's apartment. When the boys got upstairs, April willingly handed the baby turtles to their parents.

"They were good babies for the first day, but they started becoming fussy when you guys weren't around." April said.

"We did what we could for them, but it was clear they wanted you, my sons." Splinter said.

Mikey was glad to have his son in his arms again. And though Hannah was Don's daughter, Leo wanted to hold her first. He had the stronger connection to the babies. He didn't want anything to happen to them.

Raph had accepted the twins being in their lives now, but he had no idea how to bond properly with them. Maybe when they were older, he would have a better role in their lives, but for now, he didn't like dealing with the crying and changing of dirty diapers.

"So what is the new lair like?" April asked.

"Oh, it's very big, April." Mikey said. "There's lots of rooms!"

"It's a very big and open living area with a good place for a kitchen. The exit and entrance is up a flight of stairs." Leo said.

"It's not too messy, but will need some time for cleaning and to get it ready to be lived in." Don said.

"But are you going to be able to take the twins with you?" April asked.

"We'll take their beds and food, we should make due." Leo said. "This lair has only minimal cleaning compared to when we first moved into the reservoir lair."

"I can't wait to see it, my sons." Splinter said.

"And we would like to see it too, when it's all been settled into." April said. "Just make sure to keep fumes away from the twins."

"There's going to be that sewer fume no matter what, April." Raph said.

"She means the cleaning fumes." Don said. "Once we get started."

"It was nice of you to put up with us all this time, April and Casey, but we've been ready for going back to the sewers for a long time." Leo said. "We'll be sure to bring you down to our new lair soon."

The guys and Splinter began packing up their stuff out of the apartment and back out to the Battle Shell. The babies were in baby carrier seats now.

When they arrived back on the street that would take them below, Leo and Mikey put the carrier packs on and they each carried a baby. Don and Raph led the way down. When they got to the entrance, Don found the electrical switch and turned it on.

Now the new lair lit up with an amazing brightness. It made it look nearly like a castle.

There could be so many things that could be added to make this place feel like home. The family would start with getting their things from the other lair, then worry about any additional things.

Leo most of all wanted to get started on the babies' room. But for the time being, they could be allowed to sleep with him or any of his brothers. They were still sleeping in the incubators, but soon, they needed to be switched to real cribs.

Splinter walked around the new lair, looking for a room for himself.

Leo noticed that his father was looking for a room downstairs. He knew Splinter liked to have his privacy for meditation.

Splinter found a room that was the farthest back in the lair. He liked the feel of it. This would be his room. And it would give his sons some space. He knew that they had all had picked their rooms upstairs.

They all spent the rest of the day unpacking some of their things from the Battle Shell and began to clean their new home.

The next day, they went back to the old lair and started getting back what was left of their heavier stuff.

Don insisted that Leo stay home with Hannah and Brian while they were collecting the heavy items. Plus Leo did want to get started on their room to be slept in. But not all of the supplies were here yet, and he didn't even have his own bed here yet. He went about trying to get as much in order as possible.

While the others were away, Hannah and Brian were showing they were happy to be left with Leo. Not much fussing at all.

It took the whole day for the others to bring the bedding materials, couch, table, and chairs down. Leo helped with the chairs, but Don wouldn't let him handle the heaviest stuff. Even though it had been over 3 months since his surgery, he didn't want to take a chance of Leo's plastron getting re-injured.

All of the beds had been brought over. Casey had even insisted on helping out by letting them have a moving van for some of the stuff, which had made the move go a lot easier than just using the Battle Shell.

The beds were all here now, but first, the boys all took turns using the brooms cleaning off the floors and dusting. After all, they didn't want the babies to be around that stuff.

Once all the dusting was done, the beds were all brought into the respective bedrooms. Leo wanted the twins in his bedroom for now. He wanted the twins' bedroom properly set up like a nursery before he would let them start to sleep in there. And he wasn't ready to let them out of his sight for long.

Now that everything was set up, it did feel more like a home, but being here would take a lot of getting used to. They hoped that they could keep this lair well hidden. And they were grateful for Casey's help in the moving process.

The lair they found is like the one in the 2007 movie, but this does NOT turn into the movie. I tried to describe it the best I could. And trying to figure out where it was was a hard task in itself, but I did my best.
