i just watched this scene a few times and it is unbelievably adorable. i love how gentle and nice Will is to Peter. They’re both seated, so Peter doesn’t need to worry about motion, and there is the bird in front of them both as something to focus on, so the attention is off them both and they don’t need to look at each other.
Will brought Peter the bird because he was worried about it. He reassured Peter that he knows he didn’t kill Sarah. Then, when he found out Peter was being victimized and feared that no one would believe him, Will says “I’ll make sure they do.” If only someone had done that for Will… Now, he has to do it for himself.
