Yes. In fact, Neighthan is probably the guy I ship with Frankie the most out of all of them.

 (It would be Jackson, but we'll get to that ship in a bit because I have a lot to talk about with it. Oh, and I also ship Jackson with someone else much, much more.)

Neighthan seems to bring out the best in Frankie, and I think she needs someone like that. That's why I love these two so much, plus there's all their cute moments together in Freaky Fusion.

Conclusion: Absolutely!
