OKAY! So isn't Captain Jack like immortal? He has some weird triangle going on with Gwen and Ianto (who he definitely makes out with), where I think they maybe all kind of like each other in a vaguely OT3ish way?

I don't know what they do at Torchwood, but I figure it's got an edge of time travel??? And in the finale Tosh and Owen died tragically. ALSO MARTHA IS SOMEHOW INVOLVED. And fandom hates Gwen unreasonably.
