## Summary

Producers of “Stuart Fails to Save the Universe” said Kaley Cuoco’s surprise return in the second episode was intended to present familiar “The Big Bang Theory” actors in radically different roles. Cuoco plays an alternate-universe Penny who leads a resistance movement, underscoring the spin-off’s multiverse premise.

Stuart, Kripke and Bert arrive in a seemingly peaceful Pasadena where neck devices shock people for anger or arguments. After being arrested and spending 30 months in rehabilitation, they are seized by Penny’s resistance group, which includes Denise and Penny’s former boyfriend Zack.
