the body language between rex and anakin when they find fives is like, so stiff. the moment they meet fives you can tell Rex wants to say more. But he can’t; he’s restricted and that’s because of Anakin. He is so uncomfortable around Anakin, he doesn’t want Anakin to be there because he knows Anakin will make the situation worse (and he does!! his outburst and lack of understanding gets Fives killed!!). Rex believes Fives and wants to say so much more–he wants to comfort him, calm him down and tell him everything will be fine. Fives is his brother, and Rex knows he can handle the situation. He also knows that Fives is afraid, and honest and just needs someone to listen. Rex didn’t want Anakin there, but he was there and that is where things went wrong. Anakin doesn’t even realize how much he was intruding in that moment between two brothers, he doesn’t even see the importance in the moment(hell it was even an important moment between Fox, Fives and Rex). He was aggressive, rude and didn’t even care what his presence being there had done. Anakin is to blame for Fives death, not Fox; his presence, his energy was so repulsive to Rex and you could tell. But Rex couldn’t speak out, he couldn’t say anything. He could only watch as a jedi got his brother murdered.
