While Bartholomew is making friends, Annabel is watching the fellow shooting things. It's weirdly calming, seeing the rhythm that seems to be involved and she simply contents herself with staring (not at all creepily or unblinking) at him.

A part of her entertains the idea of saying something, telling him she enjoys watching him or, at the very least, a hello, but she is not actually doing that well on the social front today, especially without Bartholomew to break the ice.

So yes, she's just going to stare awkwardly.
