I think this is the first mention of Justin liking Star Trek? Well, he does, and his love for it is rivaled by only one other character...
I also think this is the first appearance of that particular jacket, and holy snap, that's a nice jacket! She should bring that jacket back, darn it. I believe it's inspired by a jacket I myself had at the time, though it eventually fell into disrepair. Rest in pieces, old jacket.
