People are concerned about Peter. They have every right to be. What Peter had to do on that battlefield would be difficult for anyone. A man as sensitive as her partner should not be forced to hurt his friends much less kill them. Another comes by as Gamora works on cleaning the ship. She doesn't check to see if Peter talks to them or not. She does offer a nod of greeting when they do leave later, wiping her hands before speaking up.

"How are you?" They're all struggling. Now the only thing she can think to do is lend some of her strength to whoever needs it. That is what she is best at these days.
