Sheldon's home!! Trouble is back

The biggest news for the Cooper family is that Sheldon and Mary are finally home from their educational sojourn in Germany. After a hellish journey home comprised of four connecting flights and many screaming children, all is well until Sheldon realizes Mandy, Georgie, and baby Cece are unwilling to move back out of Sheldon’s bedroom. That leaves the garage and sofa as possible sleeping options, with Sheldon phoning Meemaw in the middle of the night when neither of these is preferred.
After Meemaw doesn’t let him stay at Dale’s, Sheldon heads back to his college dorm room – only to be greeted by another student who’s been crashing there. Sheldon immediately questions the unknown student, who claims it’s his room instead. The two bicker for a while before bonding over an unreleased video game, with Sheldon deciding that maybe he can tolerate having a roommate after all.
