Uhh, Martin? You don't even know what faith your fiance belongs to? This does not bode well... Maybe it's time for you to have some conversations with your future wife.
That said, I think a more likely conclusion to this story than "Martin opens his mind and accepts Gabriella even if he doesn't agree with her" is "Gabriella is flimflammed by a fortune teller and Martin has to save her somehow and wasn't Gabriella silly." And even though that would be stupid and diminutive, it would kind of be worth it to see a flimflammer. This strip hasn't had an antagonist since Tori, and she was awwwwwwesommmmme!
