Of course, Buffy heard about what happened and as soon as she did, she goes up to AF to see Steve, to figure out what happened and to see how he's doing. The only time she'd ever been shot...well she knows how she'd felt when Willow had flayed Warren alive and she suspects that Steve's feelings like somewhere between that and...upset. She shows her ID at all the correct check points, barely bothering to flash it by the time she gets to the last one, but once she's through that, she stops short a few feet in front of Steve.

"Hey...Boss." To anyone that doesn't know her, she might sound timid. She's really just treading carefully, trying to figure out how he's handling things so that she can respond with what he needs rather than what her gut tells her.

"Can I join you?" Because maybe he wants to be alone, which doesn't necessarily mean she'll leave him alone. It's all about getting a feeling for where he's at.
