So Tennant was on the Friday Night Project, and he was guuud! And he wore a waistcoat! And was tied to a bed in a t-shirt and pants! Joyous!
Anyway, here is the new Partners in Crime snippet that was shown!
Donna: But if we go down in that they'll just haul us back up again!
Doctor: No, no, no. There's a lot of controls for the sonic cage, I'm the only one who can control it... Not unless she's got a sonic devise of her own, and thats very unlikely...
[Miss Foster stalks the halls with her own sonic devise]
Foster: Out of my way
And there we go!
As soon as I find the whole episode, it'll be up on PlanetGallifreyTV
