I'm just gonna pretend that s2 ended with the order getting back together after Jesse and Petra leave for an adventure. I'm gonna say they come back to find Axel, Lukas and Olivia are there wanting to make the order whole again.
Also they have a fun festival or ball, and everything's back to normal.

And then let's be real they probably get attacked by the newest threat because they just can't catch a break can they- and aw man now I wanna write this
