Honestly, the Zaith'isk is really annoyingly implemented.
If you let Lae'zel go into it because you're not a jerk, you miss out on the powerful bonus of making all your Illithid powers take a bonus action instead of a standard action. Whilst having the potential to harm her because apparently the Dream Visitor doesn't care about Lae'zel as much as you (Even though they apparently appear to everyone in your camp, since they all reference them appearing in their dreams)
If you don't let Lae'zel go into it, you miss out on the information you can acquire about it from succeeding some skill checks. Information that without which makes certain dialogue options make no sense (When persuading Lae'zel in front of the Inquisitor and later when confirming that Voss is correct about the Zaith'isk)
It just feels like a complete mess of a scene where you are seemingly punished with any option you pick.
