Splinter approaches Raphael, looking at the girl who was sleeping in the arms of his mutant son, Splinter has always known that Raphael has a tender and very big heart, he is a loyal mutant, and when he gets attached he is capable of becoming almost obsessively attached to the person who receives his attention, in this case, the girl who is sleeping in his arms.

Splinter doesn't even try to get too close to the girl, he knows very well that Raphael wouldn't hold back and would try to attack his father too, at least verbally, to protect this girl.

"So you've known her for a long time? This is where you went when you disappeared..." Splinter whispers, while watching the girl change position in Raphael's arms. "How did you meet her? Why didn't you say anything? These are the questions that matter most to me." Splinter whispers, not taking his eyes off Raphael.
