Another vote here for Ianto.
He Sweet, Funny, Stoic, Manly, Loyal and intriguingly guarded.
Also, he's totally *phwoar-some*! What more could one possibly want? He's ace!
Toshiko has rapidly become my second favorite over the course of this series. She seems much more well rounded than in Season One. Again, Stoic is a word I'd use to describe her, with an underlying optimism that just can't be quashed no matter what. She rather reminds me of Willow, from Buffy, in that respect.
Next, Gwen. She really does do the whole *Empathetic* thing extremely well. If only she'd stop doing the ridiculous doe-eyes at Jack, she'd... well, she'd still be third on my list, but not by such a large gap.
Fourth is Rhys. I just have an enduring warmth for him. He seems like a good sort.
Fifth, Owen. Last year, I'd have placed him absolute bottom, as I simply couldn't stand the sight of him. This yea... I dunno why. He just seems to have grown on me. He doesn't seem quite the hugely self-centered arsehole he did, last season.
Absolute Last, and by a phenominal margin - Captain Jack 'Jazz-Hands' Harkness. As a guest character on Doctor Who, he works. But that is a much camper, fluffier show. Whereas, he's just WAAAAAAY too Sylvia Young for Torchwood - and seems hopelessly miscast as the big ol' action hero.
As I said in another post... him as Jack, is like watching Zsa Zsa Gabor playing Xena -Warrior Princess.
Doesn't work. Ridiculous beyond words, dahlink.
