Jensen on Jo:
And I know that Alona's husband made the comment that Jensen loved working with Alona and loved the idea of Jo's character and that he told them he'd do anything in his power to get Jo back on the show...don't know how long ago that was, though.
Source On whether he'd sing a few bars of REO Speedwagon (Asylum Con)
Jensen very cleverly avoided the request by shouting up to the balcony:
Jensen: "Alona, you up there?"
Alona: "Yeah!"
Jensen: "Yeah, thanks for that!"
Alona: "You're welcome, babe."
Source TWOP 4x03 Recap:
Dean's brain doesn't know how to compute Deanna's amusement at the idea of John Winchester mixing it up with spirits, coupled with Samuel's mild contempt for the 'nice, naïve civilian'. Oh Grandpa, if only you knew. Mary scoffs at her father. "So what -- you'd rather me be with a guy like this?" Despite what a faction of the fandom scribbles in its LiveJournals, Dean's incest taboo is in strong, working order. "What? No. No. No no. No." I want to hand it to Jensen Ackles and
Amy Gumenick. These two young, beautiful humans never for a moment give me a vibe that there's any sexual attraction between Dean and young Mary, yet they have plenty of non-romantic chemistry, enough that I wish she the actress could have been cast as a love interest for him. Don't misunderstand, though -- there's never a moment I stop thinking she's his mom, even though she doesn't know it. There's never a moment I think he's forgotten he's her son. Bravo to them both (and to the craft services people who in no way sprinkled
saltpeter on their lunch).
