Cap. Jack is the best character from new who and is the only other character ever to be able to match the Dr...he is the most un explored character despite the air time he gets...

this character is just perfect, a morally grey guy forced to live forever to suffer forever to love and lose everything to be tortured by his past...he wants to be a hero but is constantly forced to do terrible thigns in teh name of greater goods...

he is the only being in the universe the dr can truly relate to and should be a full time companion again ...

a few things that need explaining, jack once described teh creatures eh knew as a child that attacked him was teh worst cretures in teh universe after eh met daleks... what can this be?

just what is jack now? as he seems to have more abilities than immorality... as he seems very mentally psychic advanced sensitive to temporal and abnormal presences...

also he has knowledge that is far beyond not just 51st century human but most things...as when him and the dr encounter the paradox machine he says " is this what i think it is " ... now that means he knows what it is and that is very very advanced knowledge on par with a time lord.. so...

jack has encountered terrible creatures, special abilities and superior knowledge ...

also i want jack vs teh return of the great beast, as long as there's evil in the hearts of man teh great beast cannot be destroyed but jack did kill its offspring.

and what does he do now... as we know torchwoods in the future so it must be recreated and the only one who can really do that is jack...so im thinking where ever he is in space restart torchwood.

Dr Who needs Cap,. Jack and only John Barrowman can play him as he is him :D...and we need some eye candy back in Who for this series hehe

I hope Torchwood does come back because I liked the way that Torchwood is more "adultified" for example it has more violence and strong language than doctor who.

hahaha and the second episode is about a sex obsessed alien! :D but yeah your right thats exactly what i thought when i saw it at first!

Oh, PLEASE bring back Capt Jack...my wife and I BOTH LOVE his character, and John is BRILLIANT in the role...

Yeh, he is good character)) Would be cool to see him in new episodes in Torchwood and Doctor Who?

I like Jack, very good character, brilliant in Torchwood. I'd like him to be a companion for a series :D

I like Jack's character
So he was made up by Steven Moffat in Empty child
made imortal by RTD in series 1 finale
got his own show and appeared in series 3 and 4
and was naked and covered in cement in the torchwood special six parter
now he's with alonso
Steven Moffat might bring him back because he made him up and is the only new series companion he likes.
for some reason I feel he's gonna come back
(fingers crossed) :)
