Are we missing something?

A pair whose friendship forever grows.

Could it mean something else?

I think it means that school and Shaggy's friendship will live on whether they're together or not.

Yeah, but why would Alexander make a gate that would separate him from his best friend forever?

He must have built a way out.

Uh, guys, Alexander the great look at this inscription.

It's a message from him.

Our bond will never break or bend.

So, my friend, it's time to return to your home.

Maybe Scooby should give it a try.

What?

Wordy, You promised you'd never leave.

Come home.

Great.

Well, you Oh!

Zoinks!

I guess friendship really did save the day.

Huggy Scooby Doo e love you guys.

You're the heart of Mystery, Inc.
