While I love Lolix (Locus x Felix), I think that Washlix could be really funny if the dynamic is:
Wash: *looking at Felix* Yeah I can fix him.
Felix: No the f*ck you can’t!
Locus: *watching from afar, obsessed with Wash* Why doesn’t Agent Washington want to fix ME?! It isn’t fair! It shouldn’t be him, it should be ME!
I don’t think Felix can handle someone genuinely liking or showing affection for him. Or wanting to fix/help him. Which is why Wash being smitten with him could be so funny and unnerving.
Wash: You remind me of myself, Felix.
Felix: Stop trying to RELATE TO ME! We’re not the same!!!
Locus: Why does Felix get everything?!
Them being a weird poly relationship could be funny too. And it’d involve lots of jealousy on behalf of Lolix, while Wash doesn’t really get jealous. Locus wants Wash and for Felix to stay away from his man, while Felix wants Wash to stay far, far away from both of them so Felix can go back to manipulating Locus in peace.
Lolix Washlix and Locington are on my mind.
