Aloth/Ridanu thoughts
(with a side of Edér)
They start sharing rooms (but not beds) at inns after Brackenbury Sanitarium
Both have occasional nightmares, neither wants to wake other party members, but they don't want to wake up alone from a nightmare either
At that point, they're the only two Awakened party members, so they feel kinda protective of each other
They also need a safe space where they can talk out loud to each other about their issues and experiences, without worrying about other party members overhearing
Ridanu uses Iselmyr's appearances as an indication that Aloth needs a safe space right at that moment
doesn't want Aloth to feel ashamed or embarrassed if Iselmyr comes out, but knows her appearances often mean Aloth is upset or frightened
it is now canon that Edér's "can I talk to Iselmyr more often" banter triggers immediately after the party finishes Two Faced. It's also canon that Ridanu responds by "trying to knock/shake the whiteleaf out of Edér's skull".
It's also canon that if Edér ever gets Charmed, Iselmyr takes over and throws Aloth's grimoire at Edér's head while yelling, "What tae Hel ye think ye're doin', ye big clod?"
