Everyone is home (the guardians, the buddies, etc). They all go outside into the yard of Mordecai and Rigby's house about a few months later. DVD shouts:

"Guys! Guess what?"

All: "What?"

DVD: "I'm a dad!"

BR: "I'm a mom!"

We now see ever so many child DVD/Blu-Ray guardians leap/bound out into the yard, all shouting gleefully.

Blu-Ray: "Isn't it great? Look! They have my stunning HD capability, and his (leans on DVD) extraordinary compact size!"

If you have anything else to add onto this, please do so. That is all I have.
