Did the engagement come as a surprise for Parsons?

I guess well adopt a monkey next.

And instead, it makes all the sense in the world!

It feels like they built towards it.

And what happens between Amy and Sheldon after that proposal?

So far, no ones been left at an altar yet, he promises.

(Parsons narrates the spin-off and is an executive producer.)

WithBig Bangentering its second decade, how much longer does Parsons imagine playing the character?

I dont think youre gonna see a geriatric Sheldon, he says.

Oh, Jesus, I think I literally just heard Steve roll his eyes somewhere and Chuck groan.

Big Bangisnt ending anytime soon, of course.

We have this contract now that goes through season 12, he notes.

Who knows what the future holds, but lets say it ends in two more years.

Its been a wonderful ride.

Im fulfilled in so many ways.

Certainly on me, maybe on the cast as a whole.

It may help the death not be quite as total.
