I completely forgot that Jester and Molly have different Eyeball situations going on (lol). CR is a mostly sound based medium in fairness to me, so until the Animated sneak peek came out, I kind of didn't notice or put together that Molly looks more like a full Tiefling with the completely red colored sclera, whereas Jester has more "normal" (not to be speciesist) white sclera. Marion, if I recall correctly, has the full Tiefling eyes as well, so I do think that's a hint about Jester's parentage I just picked up on lol. Only a couple years late.
I wonder if they'll address it in the animated show. That would be a good jumping off point to drop breadcrumbs about Jester's mixed heritage and her missing/absent father. They could have a little, "Oh My God Nott, you can't just ask a tiefling why their eyes are white!" Mean Girls moment. Her hellish rebuke being Ice instead of Fire is also abnormal so that would be interesting for them to discuss. They have to lay some sort of groundwork for The Gentleman reveal and that would be a relatively subtle way of doing it. The somewhat random way the reveal happened in the campaign is awesome but for a tv show they need to add at least a little bit of a hint beforehand (more than just him being Blue and Bi lol).
It could be during a conversation where Molly spins some bullshit about his past. Like that bit from the beginning of C2 E6 where he lies about praying over his swords, admits he wasn't honest with them when he first met them about his family being from a long line of priests, then proceeds to continue to lie his ass off by saying rather than priests, they were the ritual sacrifices who ran away and that's why his blood is special.
That scene has the amazing foreshadowing line:
Beau: Oh my god, you killed your whole family?!
Molly: I didn't kill my whole family.
Beau: Oh, okay. Never mind, keep going. I'm sorry.
