There are entirely TOO MANY TO CHOOSE, so off the top of my head I’ll pick a really shaky top 5 from each of them (in no particular order). I’ll probably remember other ones later.
Jensen
1. “you keep ur “subtext” to urself, sir. I’ve told u…I’m not that kinda girl …wait, what. Crap.” -Twitter
2. “I love you, Misha. I mean, honestly, it’s from the bottom of my heart that I say that. Seriously, it’s not stopping.” -MTV Top 10
3. “That’s not a very nice thing to me in front of my Valentine on Valentine’s Day.” (Assuming that’s what he said) -that fucking HousCon16 video
4. “He’s so cute, you know? Like one of those little teddy bears, you just wanna stuff him in your pocket and take him home with you.” (I’m melting as I type this) -JibCon 2011, Jensen crashes Misha’s panel
5. (About the boat trip) “Another one included him having to…having to strip down and put some goggles on……because….because we were attached to something.” -MinnCon2015
Misha
1. “I have loved doing the intimate scenes with Dean or Jensen over the years the most. There’s something about that dynamic that just seems to work really well and I’m sorry to see it go.” (2011, probably when Cas was almost permanently killed off)
2. “ Me and my Deck Swab. (or as he likes to be called: Cabin Boy)” -Twitter
3. “It warms the cockles of my heart. Words chosen carefully.”
4. “When I first did it (staring) I was imagining that I was like looking into his (Jensen’s) soul”
5. Not really a quote but when he was reading “We Are Not Ourselves” at the Barnes & Noble event and Matthew (the author) purposefully picked out a passage that had the word “bowlegs” in it and Misha knew it was coming so he tried to end the chapter early but Matt was grinning and was like “no, there’s more!” and it would have been absurd for Misha to end it there because he’d read like 2 pages, so what’s two more paragraphs???? and then he said “bowlegs” and stopped to compose himself and it was beautiful
(the whole “Come fly with me!” “My feet are stuck!” exchange is still one of my favourites, but maybe I’m biased.)
