Lookie:
Jack Harkness meets Peter Petrelli This does pose the question: what would happen should Heroes and the Whoniverse collide?
(Minor S2 spoilers for Heroes)
Mohinder and Peter would make for excellent recruits to Torchwood. They’re certainly qualified - oh so pretty but dumb enough to bringing about the destruction of humanity, they blindly trust the last person they spoke too, the slash can hardly be described as subtext. Plus Peter’s indestructible and prone to standing on top of tall buildings and angsting, and Mohinder’s been known to idiotically shoot people he’s working with and has an ex partial to a bit of head slicing. They’d fit right in with the team.
(I know I should really stop giving Torchwood crew crap. It’s like kicking an ugly puppy - it’s just so easy there’s no satisfaction.)
Meanwhile, Claude would be laying low in Sarah Jane’s attic, unbeknownst to anyone but Sarah and Mr. Smith. Sarah can’t help shake the feeling that she really needs to tell him to shave and put on a leather jacket and Luke’s trying to work out who keeps on nicking the leftovers from the fridge, and his pocket money from out of his pocket.
In Claire the Doctor has the perfect companion. Teenage, blonde and cheery but - unlike Rose - indestructible and capable of living forever and never aging. So, unless there’s some rift action, they can be together forever. Of course Claire’s father would make Francine Jones look positively like a saint and Mr Bennet’s hardly going to let Claire run around space and time with some grinning idiot without a chaperone, leading to the inevitable capslocked meeting of HRG and a Dalek:
“EXTERMINATE!”
“YOU THREATEN MY FAMILY?!”
(Since it’s now been established that HRG is too awesome to die, my money’s on him).
Sandra and Mr. Muggles will come along for the ride too, and Lyle will wait patiently behind for them all, wondering if anyone remembers he exists (what Lyle doesn’t know is that a freak childhood accident involving the TARDIS has left him perception filtered - he's there, but nobody notices).
It shall later be revealed that the Doctor’s not the first Time Lord the Bennet family has been in contact with. The Haitian’s been active on Earth for years and Angela Petrelli’s the stopwatched Rani (it’s those pesky Time Lord genes that prompted Nathan to get into politics).
And while this is all going on, the TARDIS will have a torrid affair with Mr. Muggles. Though the affair will end badly once the TARDIS finds her soul mate in fellow space-time traveller, Hiro Nakamura.
