Don and the Amalgamate wake up and Don starts to go. The Amalgamate stops him.
Don: What is it bud?
The Amalgamate whimpers while making a sad face.
Don: You want to come with me?
The Amalgamate shakes its head yes.
Don: Alright. Come on.
Don and The Amalgamate meet up with Gaster.
W.D.: Why is that thing following you?
Don pets the Amalgamate.
Don: He wouldn't let me leave otherwise.
W.D.: Fine. Just, go make sure Mrs. Snowdrake hasn't left her room.
Don: Alright.
Don and the Amalgamate go to Mrs. Snowdrake's room. Mrs. Snowdrake is crying. Don goes in and the Amalgamate follows.
Don: Mrs. Snowdrake? What's wrong?
M.S.: They won't let me go see my Snowy.
Don: Why?
M.S.: They say that he wouldn't like me.
Don: But he's your son.
M.S.: I know.
Don: I'm gonna go have a talk with Gaster.
The Amalgamate bends over.
Don: You're giving me a lift? Okay.
Don and Mrs. Snowdrake gets on the Amalgamates back. They reach Gaster who is near the core.
Don: GASTER!
W.D.: Yes Don?
Don gets off the Amalgamates back.
Don: WHY WON'T YOU LET THE PATIENTS GO TO THEIR FAMILIES?
W.D.: Because they don't need to leave.
Don: Why not.
W.D.: Because I need them for my next project. A portal to another world. Now that you know about it, you must be thrown into the void.
Don: I'll stop you.
A portal appears behind Don and Gaster attacks Don. Don dodges and Gaster is holding on to the edge and Don grabs Gasters hand.
Don: Don't worry I've got you.
W.D.: Let go of me!
Gaster brakes free of Don's grasp and falls as the portal closes. Don gets back on the Amalgamate and leaves a note that says "Gaster is gone." He tells Alphys what happened. Alphys kicked him out after he gathered his stuff.
Alphys: I NEVER WANT TO SEE YOU AGAIN!
Don, Mrs. Snowdrake, and the Amalgamate go to Snowdin and reunite with their families. Don tells Papyrus he was fired.
Papy: Don't worry. You will be able to get another job somewhere.
Don: I've seen some empty stations with grills.
Papy: I've already convinced Undyne that if you were fired to let you into the Royal Guard.
Don: Alright.
And that is how Don got his current job.
