Hi -
Personally, I didn't think Apollo and Sheba got together very soon after HOG. I figured it would happen later in "season 2". Why? Because, and don't flame me because I never did the hard math, I just figured Serina hadn't been dead for a year yet. I just kind of thought Apollo would need another 6 months before he'd be ready to "move on". Even though Apollo has feelings for Sheba, he still wasn't healthy enough to deal with them. I mean, Sheba just called him on his "death wish" thing, would he be over it right away? Or would it take more time to break a habit he's had for a year? And how would Boxey feel about Sheba "replacing" his mom? I got the impression that Boxey never knew his "real" father and excepted Apollo easily enough, but would the child be so excepting of Sheba? But these, of course, are questions for "season 2"...
I'll stop rambling now...
