[1]What do we know about Princess Bubblegum? Is she really as sweet as she looks or is she something else? Give evidence on her past or give a good theory on what her past might be.
Evidence[]
PB can speak German, which she has at least 4 times in the series. She said "Ich bin hier," (I am here), and, "Ich bin so gluecklich! Ich koennte, ich koennte-" (I am so happy! I could, I could-) in What Have You Done, "Auf Wiedersehen" (goodbye) to Finn over the phone in Go With Me, and she counted in german from 35 to 41, "fünfunddreissig, sechsunddreissig [...] einundvierzig" in Stakes, Part 7: Checkmate. She also had a sign in front of her house the read "Willkommen" (welcome) in Bonnibel Bubblegum.
PB also have some sort of past with Marceline since she knows Marceline in "Go With Me" and Marceline even gave her a shirt that the Door Lord stole which means it is very valuable for her in "What Was Missing."
Opinion[]
I think that PB must have spent some time in Germany because Earl of Lemongrab has a somewhat European accent. Plus, PB also speaks it.
She probably made Earl because she was lonely in the castle but ended up making a mistake, she is apparently too busy in her expiriments to realize that she is lonely.

She may be Ice King's favorite princess because she reminds him of Betty.
