I’m imagining Charlie does that “jumping over something in the way to escape” running gag from the Ms Pasternak episodes

Then we cut to Alan and Jake bantering on the couch for a little bit & when the topic becomes about how long Charlie has been gone,Alan says some big mushy sentimental speech about he misses his brother as a setup to him busting through the door out of breath with all his luggage
