Even though she wasn't thinking about it, Heather's expression seemed to be permanantly screwed up as she watched him remove the bandage she'd thrown together as a quick fix. The wound was still bleeding due to how deep it really went, though it wasn't pouring by any means. That was a good thing, at least. And then there was the bruise, and Heather suddenly went from looking disgusted to appearing very sympathetic. It had to hurt like hell, and she knew it just based on Sam's own facial features as he attempted to pull his shirt up.
"Yeah, here," she said, scooting closer so that she was sitting right next to him. She wanted to do this as gently as possible, so she coaxed his uninjured arm out of the sleeve first. After that, it was incredibly easy to get the shirt off the rest of the way, over his head and off the other arm just by letting it fall on it's own.
