I can't help but feel the higher Jeph builds peoples' expectations with this storyline, the further they'll fall when he pulls the rug out from under them.
So, the great (great!) Billy Wilder had a piece of writing advice;
The more subtle and elegant you are in hiding your plot points, the better you are as a writer.
I think Jeph's doing an admirable job of that at the moment. Important to note; Shipping is happening fairly strongly in-universe right now.
So this can
1) Bubbles doesn't have feelings for the Pugnacious Peach, but ends up feeling pressured into it, Problems Occur, moral lesson Shipping is Wrong
2) Bubbles has feelings for Faye, is encouraged into admitting them and
2a) Faye reciprocates, which is... a path that is quite fraught.
2b) Faye doesn't, which is Problematic
3) Bubbles doesn't have feelings for Faye, realizes she doesn't have feelings for Faye, and this is all just a moral lesson Shipping is Stupid.
And of course I could be missing some. But I don't think 'pulling the rug out from under people' is the most likely choice. It's simply one more potential item on the menu, and I'd argue 3 is the least likely, just because it's the least interesting.
