As a casual observer not very well versed in H3 lore, I genuinely wonder what Hila thinks about all day. Ethan always says exactly what he's thinking in the moment but Hila stays silent a lot. At least in the clips I have seen.
I have always believed she clearly has bad judgement for thinking Ethan is decent enough to stay married to and procreate with, but the more shit Ethan gets up to and the longer she outwardly tolerates/supports it, the more I think she actually agrees with him on most things but has the sense to realise she'll look bad or dumb if she opens her mouth.
I'm starting to wonder if she's the "better to stay silent and have people wonder if you're a fool" to Ethan's "rather than open your mouth and prove you are one".
