"You told them where we were!" Jyn finds herself quickly shouting but her temper has always been difficult to contain. It's not like her voice wouldn't have carried in the small ship anyway. Might as well invite everyone else to their discussion.

"They sent you to kill my father!"

She doesn't let him go, even if her hand falls. It serves to drag him forward a bit more, but her grip is like a vice, eyes flashing with accusation. He didn't kill her father, he brought her back to the ship and maybe that is what is setting her off the most. Grief mingled with the uncertainty of something she'd never experienced before: someone coming back for her.
