Seth Rogen, Rose Byrne tease what is to come in 'Platonic' season 2

The besties are back in Platonic season 2.

The duo previously played husband and wife in the 2014 comedy Neighbors and its 2016 sequel. In Platonic, they play strictly platonic, codependent best friends Sylvia and Will. Byrne says chemistry is "really ephemeral" and she was lucky to actually "really hit it off on screen and got along as well as friends off screen" with Rogen.

While Sylvia and Will's friendship was rebuilt and strengthened throughout Platonic season 1, Rogen says the pair still "have a lot to learn" throughout season 2.

Platonic season 2 premieres its first two episodes on Wednesday. New episodes arrive weekly through Oct. 1.
