Because I rarely pay attention to the guests (they're totally secondary to the fun we have in our little volunteer group), I only just realised that not only will be most of the cast of The Expanse at Fedcon, there'll also be 3 actors from ST:Disco! Plus, the 2 dudes from Killjoys, Bruce Boxleitner & Mira Furlan from B5.
I really like Killjoys, and Wilson Cruz has been a fave since MSCL - maybe I can upgrade my volunteer autograph vouchers to get theirs. Hmmm... Should have planned ahead! :)
