Panel 1 explains that Wilbur is watching Modern Family, so presumably, it is Sofia Vergara who reminds Wilbur of Fabiana. I'm just guessing. I see on Wikipedia that she was born in Colombia, just like Fabiana. I've never watched Modern Family, so let me see if I can find a clip on YouTube.
Wow! I am definitely going to start watching this show. She is hilarious! In fact, the only difference between Sofia Veraga's character and Fabiana is that one is better written.
