So are we kinda-sorta back to thinking that Weller IS Carol Marcus' dad??
Or Harcourt Fenton Mudd??
(I think I'm more confused now...
I'm guessing he's Carol Marcus's dad. At the very least, I think it likely Alex Marcus is going to a prominent character in the movie, based only on the fact that his name was in bold print when April said it, implying he's going to be a key player. Twenty years is enough time for Commander Marcus to become Admiral Marcus, a "CEO type" who could have his own starship.
