Oops - apparently I can't count this morning.
I should really be in bed instead of posting, but I've fallen behind (again) and need to catch up on a few things here.
That capture of Quentin and Willie should be easy to track down because Willie didn't appear much in 1970RT. Also, Quentin may have only worn that suit during Leviathans, which would really narrow things down. If Sara doesn't have a chance to answer before I get a chance to look, I'll post the ep number later...
