1. Is there a hairbrush that Julia can see that she can steal a few hairs from?

2. If the Doctor can stage a distraction, perhaps involving the bird (Julia would ask him on the inbox), could Julia check out the compartment? (Distraction would be along the lines of asking Retha if she might trust him for a moment to groom the bird a bit himself, and then some chatter about how long she and Firewing have been connected, etc. he might "accidentally" drop the brush, laugh at his clumsiness, stall another moment or two as well.)
