I hope Marble Pie appears so we get a resolution to her heartbreak in Best Gift Ever. It would seem cruel to have that scene without a follow-up. Maybe Marble Pie and Sugar Belle could become friends, much to Bug Mac’s shock and surprise.

I know this ain’t certain - but knowing how predictable this show can be at certain times and what the episode title seems to imply (“The Big Question”, meaning marriage proposal), it’s not that far-fetched. But then again, this could just be about Big Mac working up the confidence to ask Sugar Belle to marry him, but that’d be a bit anti-climatic, cause I’m sure the fandom would wanna see an ACTUAL wedding, not just a proposal.

I don’t want to be that guy, but are we sure that this episode is going to be about these two getting married?
 
For all we know, the “Big Mac” question might be something like “Where should we plant the trees?” or something like that.
