Personally, Once I saw that the tadpoles they were using on us were special in such a way that they could be triggered by a remote psionic key to instantaneously evoke a full and complete transformation in a matter of seconds, that was all the narrative proof I needed to know that urgency was absolute. We see it in the ship, at the start.
This.

Happy to hear that dialogue has been added to make things less urgent, although that doesn't necessarily address @Niara's point. Unless it does...I haven't played patch 4 so idk exactly what the dialogue is. Good point that we've already been listening to panicking companions (especially Lae'zel, who seems like The Expert on illithids) up until that point so are less likely to really listen to Wyll.
