My favorite character so far is probably Tim Pennington, though, mostly because I can't yet peg him and really can't make my mind up whether I like him or not.
Most definitely agree. I do like him, find it hard to feel sympathy for some
of the mess he finds himself in, but he certainly comes across as very real person.
I'm also a bit biased because my New Zealand friend, Lana Pennington-Brown, is the namesake of DS9's canonical Pennington School, so when Tim was realized as a ST character, I was instantly intrigued.
