Raphael's Remorse.

Splinter's death has been a hard shot for the turtles, who had to deal with sadness and nostalgia.

One of them though, is silently suffering more than the others, and that's Raphael.

He was the only one of the brothers who saw the father being stabbed and killed in front of his eyes, and the remorse for not acting faster is eating him from inside.

Time has passed, and Leonardo, Donatello and Michelangelo started to move on, not realizing to leave their hot-head brother behind...who actually wasn't seeming to look like a hot-head anymore at all...

Just one person is going to understand first what is bothering Raph, since she was just next to him when the tragedy happened.

Will they manage to get their hot-head back?
Or will he remain an empty, passionless shell forever?
