Chapter Four

Donatello's Suspicion

A few hours later, the turtles and Mona had packed the Battle Shell up ready for when they were to return to New York and were doing their training.

Splinter had them all standing in a straight line and they were doing different, blocks, jumps, punches and kicks as Splinter shouted out different names of the moves.

April and Casey sat on a tablecloth on the grass nearby and watched them, "Mona's really getting into it isn't she?" said April as she watched the Lizard Lady stand between Leonardo and Raphael and do the movements. Casey agreed, "she sure is" he said.

Splinter tapped his stick as he called out the different moves, then finally slammed his stick on the ground shouting "And finish!"

The turtles and Mona landed back on the ground and bowed to Splinter before kneeling over and gasping for breath.

"Whoo! That was intense!" said Michelangelo

"Tell me about it" said Donatello as he started to do some warm down exercises.

Leonardo stretched his arms up as he tried to warm down his body after the intense training.

Often training helped relive some stress and unwanted anger, it did help a little bit after all he had been feeling after seeing Raphael and Mona kiss, but he still felt horrible.

Splinter then walked over to the table cloth to join April and Casey whilst Mona and Raphael walked off towards the woods.

Leonardo saw them walk off and grinded his teeth, seeing them walk off hand in hand, it made him feel sick with jealousy that his younger brother had something he wanted. Yet mustering all his emotional strength he forced his jealous feelings away.

Donatello noticed him watching the lovers walk off into the woods and saw he looked agitated, "Leo?" he asked tapping his brother's arm.

Leonardo turned to his brother, "What?" he asked.

"You ok?" asked Donatello "I noticed you watching Raphael and Mona...you know about them right?"

Leonardo felt his throat start to hurt and he fought the tears that started to form in his eyes, he felt like collapsing to the ground and crying in Donatello's arms, but using every will and every emotional strength he had, he managed to hold in his emotions and appear normal.

"Yes..." he said "I know about them Donnie, not hard to tell really..."

His eyes followed Raphael and Mona who held each other's hands as they walked into the woods and disappeared from view.

"Are you ok with it Leo?" asked Donatello in a worried voice analysing his brother.

"I'm fine Donnie" said Leonardo "I'm happy for them" Donatello wasn't convinced as he studied his brother's face but he decided to leave Leonardo be.

He then watched Leonardo walk towards the farmhouse, "I'm gonna have a rest Donnie" he said "come and get me when it's time for more training"

"Ok" said Donatello watching his brother walk towards the farmhouse; he folded his arms as he watched his older brother walk away.

"He's bothered by it" thought the brainy turtle, "Leonardo's good at hiding his true feelings, I know he really liked Mona, he seems to be doing well at hiding his emotions, but what if it gets too much?"

He looked over to Splinter who was talking to April and Casey, "I wonder if I should tell Master Splinter?" he thought.

"No, no" he scolded himself "I shouldn't, Leo's got to make the choice, and if I know Sensei, he's good at spotting emotions, and I know how those two have a very strong father and son bond"

Donatello sighed again then noticed Michelangelo following Raphael and Monalisa into the woods.

"Darn it Mikey!" he groaned as he watched his baby brother run off into the woods, he followed the young turtle into the woods until he saw him stop by some bushes.

"Mikey!" cried Donatello in a loud whisper "what the shell are you up to!"

"Just observing the happy couple" said Michelangelo.

Donatello tiptoed over to Michelangelo and ducked behind the bush, they then saw Mona and Raphael sitting together under a tree talking, Raphael was sitting on a small rock with Mona in front of him and he was stroking her shoulders and hair.

"I'm sorry Don" said Michelangelo "I just think they're so cute together and it's kinda cool seeing Raphael acting so sweet!"

"Don't you think this is being a little nosy?" asked Donatello "those two have a right to some peace and quiet!"

"Oh be quiet braniac!" said Michelangelo "don't you think they're cute together?"

"yeah, but..." said Donatello but he sighed knowing Michelangelo wouldn't listen to him.

They watched their brother and lizard lady as they talked and Raphael massaged Mona's shoulders, and ran his fingers through her hair.

"They're really in love bro" said Michelangelo "they don't want to take their hands off each other" Donatello nodded but he looked worried.

"What is it bro?" asked Michelangelo, "What?" asked Donatello "You look worried" said Michelangelo.

"I'm a little worried about Leo" said Donatello "He seemed agitated when he watched Mona and Raphael walk off together"

Michelangelo looked at his brother, "So?" he asked, "I think Leo's upset about Mona choosing Raph" said Donatello

Michelangelo looked uncomfortable, "well, Mona can't date both of them can she?" he said "And from what I saw the past few weeks, she and Raphael did flirt with each other a lot, it was kinda no surprise when they finally ended up together"

"I saw that too" said Donatello "but Leonardo liked Mona too, I saw it in his eyes, and remember the day he took her to Coney Island Beach? He looked disappointed and told us he was tired"

Michelangelo thought back to that night and remembered "oh yeah, I remember" he said.

Flashback

Michelangelo was sitting on the sofa watching the TV whilst stroking Klunk with one hand and eating a Chilli pizza, Donatello was in his medical room but had come out and was sitting at the computer nearby.

As he stared at the TV he noticed Leonardo walk over and sit on the sofa, Michelangelo could smell seawater on him and some strands of dried seaweed was sticking to his shell.

"Heya bro!" said Michelangelo cheerfully seeing his older brother "hey" said Leonardo quietly.

"Did you and Mona go anywhere nice?" asked Michelangelo

"Yeah" said Leonardo "I took her to Coney Island beach"

"Coney Island!" cried Michelangelo

"Coney Island!" he heard Donatello repeat "the place where we fried Nano!"

"The beach next to the amusement" said Leonardo. "We went swimming in the sea under the stars, then fireworks were let off above the sea by some young people having a party on the beach"

"Nice!" cried Donatello "wish we'd been there! That must have been a sight to see!"

Leonardo nodded and rested his elbow on the arm of the sofa as he stared into space .

"Sure was" he said "a real sight to see" Michelangelo chewed his pizza slowly as he analysed Leonardo and his older brothers spoke to each other, he could hear his voice was quiet and almost had disappointment in it, but he didn't know why.

"You seem kinda sad, I can tell it in your voice" said Donatello "I thought you'd be hyped after seeing something beautiful"

Leonardo sighed. "It's nothing" he said "I'm just tired" Michelangelo saw Donatello look sceptical then he saw Mona come out of the washroom.

"Leo!" Michelangelo heard her shout "the bathrooms free"

Leonardo jumped up from the sofa "thanks Mona!" he called back, he then looked at Donatello and Michelangelo

"I'm just a little tired" he said "I'm gonna have a shower, then maybe take a nap before Splinter calls us out for our second lot of training"

"Ok bro" said Donatello and Michelangelo together, as they watched Leonardo walk off to the washroom.

End Flashback

"I noticed Leonardo seemed kind of sad" said Michelangelo, he looked back at Raphael and Mona who were still talking and Mona was leaning against Raphael's plastron as the red masked turtle stroked her hair.

"If Leo's heartbroken over Mona choosing Raphael, I wonder how he's gonna take it, it does take a while for a broken heart to heal" said Donatello.

Michelangelo bit his lip, "Do you think he'll be alright Don?" he asked.

"I dunno" said Donatello "I've seen Leonardo really angry and saddened before, but not like this"

"Do you think we should talk to him?" asked Michelangelo "or maybe Master Splinter"

"No" said Donatello "I tried talking Leonardo but he kept telling me he was ok and that he was happy for them, but something tells me he's really upset, as good as he is at controlling his emotions and hiding his true feelings, he can't convince me"

Donatello then took another breath "And we shouldn't get involved, if Leonardo doesn't want to talk to anyone we should just leave him be, and maybe we should leave it up to him if he wants to talk to Master Splinter"

"Ok" said Michelangelo looking at Raphael and Mona again but also worried about Leonardo.

"Come on Mikey" said Donatello placing his hand on Michelangelo's shoulder "let's leave Raph and Mona to themselves, they deserve some privacy"

"Ok" sighed Michelangelo as they crept away from the bush and back towards the farmhouse leaving Raphael and Mona alone.

Looks like Donatello and Michelangelo are getting worried about Leonardo.
