(Warning: Sweet Raph ahead. I really hope I didn't make Raph seem OOC in this post XD I just wanted to show that sometimes he can't keep his soft side from showing when with Ava.)
Raph initially tensed when Ava moved to wrap her arms around his neck, pulling the turtle into a hug. Once it finally clicked what was going on, he raised his brow in surprise while he stared down at the top of Ava's head. Very hesitantly, he went to return the gesture by bringing his arms around her waist; giving her enough time to pull away if needed. He blinked a few times as Ava murmured her thanks, telling him how much it meant to her that he stuck his neck out like that for her brother.
This caused a small smile to flit about Raph's lips, "It's no problem. He means a lot to you and if scaring off some dorks for him makes you happy, I have no problem doing it." He told her in a quiet voice, having unknowingly let his soft side show in this moment. Raph didn't really consider the fact that he had broken one of his family's most important rules, he had done it to help Jake. Help people, that's what they did, right? Besides it made Ava happy to know that her brother wouldn't have to deal with those jerks anytime soon, which in the end made Raph happy.
Ava's lips soon came in contact with Raph's cheek, giving him a small peck. But that was all it took for the turtle's face to light up like Times Square. Seriously, his face was as red as his mask for a few seconds. He took a step back while tilting his head down to hide his blush, rubbing a hand against the back of his neck. "Thanks..." He said in response to her words, ones he did not often here, not even from Casey. But then again, their relationship was far different than the one he had with Ava.
However, the turtle quickly snapped to attention when he heard Jake tease them; looking at the boy with narrowed eyes. It wasn't like the glare he had given the bullies, it was similar to the one Mikey got when he was trying to press his brothers' buttons. So nothing severe. Raph wouldn't have to do anything though, Ava taking off after her brother as he sang.
His eyes ridges raised when she tackled him into the bean bag, having smacked a hand over his mouth to silence him. It didn't do much good however, Jake still managing to get the words out in a muffled voice. "It's not like that, Jakey!" She scolded, "We're just friends, Jakey." Raph nodded along to this, siding with her. "Besides" Raph said as he gained a smirk, "I don't think she could handle this." Judging by his tone, Raph was clearly joking, something he was known for.
However the amused look Raph had soon dropped as Ava made mention of the friendship bracelets she had made for him and Mikey. Of course, his brother would probably tease him over such a gift, but it was thoughtful nonetheless. She had taken the time to hand make something for Raph, and although he didn't have the bracelet on him now; he'd add it to his weapon's hilt soon. "It was cool" Raph told her with a slight smile, one which assured her that he had liked her present.
