I personally think Jeckyll has the hots for Victor. That's one of the things he's trying hardest to suppress. Go back and watch the scene where they first enter Jeckyll's lab. Watch how Jeckyll absolutely *spits* out the line "The things we do for love…" as he's now helping Victor with the Stupidest Idea Ever.

My favorite character on the whole show. No crazy powers, no hidden talents. Just a smart, gentle man with a wonderful gift for empathy beyond those of his compatriots. I cried through the whole scene. At least they didn't kill him off. I adore Lyle so much.
