I need to be out there looking for that rogue universe.
Orbo: Hey, Scrabby.
Orbo.
You're up, mate.
So much for art.
You did the right thing.
I just didn't want to see her hurt.
I saved Marceline by putting on the crown.
But it could have easily backfired.
And in the long run, I did hurt her.
Was there another way to save her?
Well, I don't know.
Oh.
On the plus side, I did get to live a thousand years
and meet the Fionna and Cake.
Aw, you weren't trying to find us.
You were trying to call your magic space girlfriend.
Right.
She wasn't always an indecipherable goddess of chaos.
She was human once.
The most amazing human I've ever met.
They still treat me like a house cat.
But I'm capable!
...and she could make the best soft-boiled egg.
Not runny, but perfectly jammy.
I can understand why you wanted to see her again so badly.
Ah, sorry.
Nothing's more pathetic than an old man
rhapsodizing about young love.
Aw, no! I'm a sucker for a good love story.
Betty and I first met at the library...
when we both reached for the same book.
You're right, it's boring.
Ha, just kidding.
And although I wasn't able to locate
the actual Armor of Zeldron,
the Wand of Dispersement,
or the freaky porcelain lamb,
I believe they're still out there,
waiting to be found.
Thank you.
I touched his hand in the library once.
Dr. Petrikov, you can't actually believe
that these objects exist.
I do.
We just need sufficient imagination to seek them.
What are you gonna look for next, magic beans?

Babette!
In a manner of speaking, yes.
Much like the Jack of legend,
I'm attempting an arduous journey into the unknown --
an expedition to find the Enchiridion.

Excuse me, Dr. Petrikov?
Oh, library girl.
Oh, you -- you remembered.
It's Betty. Betty Grof.
Um, I was wondering if you could sign my book.
You've read my work?
Oh, yes. I was fascinated by the runes on this vase you found.
Perhaps the designs could actually be pictographs.
A clue on how to find the selkie's cove.
Hm!
You know, I never thought of that.
I wish I had run into you sooner.
Haha, maybe you should come on this next expedition with me.
I was going to leave next week
on a six-month trip to study petroglyphs in Australia.
But going on an expedition to find an ancient artifact
with the Simon Petrikov,
that is a once-in-a-lifetime opportunity!
So yes. I'll go with you!

Wow, you'd just met and she dropped
everything to go with you?
