I'm really disappointed, going into the Temple of Ilmater, that there's no dialogue option that accounts for the possibility that the player PC might be a worshiper of Ilmater. Which, in my headcanon, my current playthrough PC (a paladin) is.

The closest I get is, "Sounds like your god would be proud of Father Lorgan."

Even "Sounds like Ilmater would be proud of Father Lorgan" would be an improvement. Opportunities to actually engage as an Ilmater devotee would be even better.
