Sasha sighed, because it was a big thing to promise, and she didn't think that she could do that. Not if her friend was going to get hurt. She looked out the window, thinking for a while. She didn't know how she could reply, feeling as no matter how she did, she'd be stuck watching him get hurt. 

Finally, she turned back to Angelo. "I will not interrupt unless it seems necessary to me." She said softly. "I can't promise it though. You're my friend. I don't want to see you hurt" She fell silent, watching him.
