Before we get to that, though, we'll check in with an old Big Bang buddy, says new showrunner Steve Holland. There will be two returning guest stars on the premiere — Riki Lindhome as Dr. Ramona Nowitzki, whose kiss inspired Sheldon to propose, as well as a surprise special guest.
"There's another guest star in the premiere, but I think it might be a spoiler, so I don't want to say it, but there is someone that Sheldon realizes whose permission he needs before he can ask Amy to marry him," Holland told TV Guide. "So we do a little bit of a flashback and see that when he left the kiss and Caltech but before he gets to Princeton to propose, he did make a stop to talk to somebody. "
Who do you think gave Sheldon their blessing?
Hint: he's a genius.
The Big Bang Theory Season 11 premieres Monday, Sept. 25 at 8/7c on CBS.
