Considering that I saw Cari reply to someone somewhere "don't worry, Caly will have multiple spicy scenes in the future" or something along those lines, I think we're definitely going to get something in the next update.
Yeah, probably not going all the way, but not only is something due with her, it's the perfect opportunity. I'm sure she and Orion will get some alone time in private chambers once they clear up who Orion is and how he freed Calypso. The Elves might not approve of a human fully, but at least respect what he's done for her so they don't lock him up.
At the end of the day, once the first part of the update is done, then we're gonna have to move on to other girls so they get their screen time. So if not now, when?
It would actually make a lot of sense since, iirc, according to Calypso's tale, the last time all 10 were together was when Yliar had them. In Hyril'ar.
Minor correction; Yliar never had them. It was the Eldari hero who had the gems and apparently used them to defeat Yliar (or at least, that's what it looked like in the story).
It'd be interesting if a gem was found there, but I don't know why 9 of them would be scattered around Eternum and 1 left behind in a different world. I actually think the Founder himself placed all of the gems, based on how an exit portal appeared when the zombie mom hugged with her kid and the mystery was solved when we acquired the 1st gem. The portals are his creation.
Maybe he's just looking for the strongest individual for reasons unrevealed, possibly then to control them via the neutral implant, and William is mistaken thinking he's trying to get the gems for himself. I mean, William never even met the guy based on how he was bitching about him never showing his face anywhere.
