About their relationship and chemistry, there’s a few that comes to my mind right now in no particular order:
– https://www.youtube.com/watch?v=hHDVFJUNVas – it’s a compilation of all the interviews they did for the TCA for season 10 and he talks about it a few times, especially around 7min. “I appreciate her more than ever, all the time…”
– There’s also this podcast that I can’t find right now but I’m sure I have it somewhere or someone else can point you out to it where David says “I think as you get older, I think if you’re lucky, if you’re maturing, the stuff that used to bother you, the little things, kind of evaporate and all that’s left is the heart. And that’s all we have left is just total appreciation of one another.”
– There’s this video too where it’s David talking about their chemistry : https://www.youtube.com/watch?v=vHhiccpR_Ag&t=20s
– This one is from the IWTB promo so it’s a bit old, but what he says is really beautiful : https://www.youtube.com/watch?v=zlXe3yv2E5E
– There’s of course the famous “for me” Paley moment
– There’s a little bit of that too in the BTS of season 10 when David explains how they work well together because they have such a long history together.
I’m sure there’s many more!
