So when Finn and Jake are leaving the nightosphere in an earlier season (before they jump in the portal back to Ooo) you can see a couple photos on the walls of hunson abadeers place

One of the photos looks like it would be Marcy's mom, but now that we know what her mom really looks like who do you guys think that woman in the photo is?

Or is that her mom, and the person we saw in stakes was some sort of guardian or relative who took care of her? (idk)

Sorry I don't have a screenshot of it or anything, I just remember seeing the photos
