i don't know what's already been established in comm so i haven't fleshed too much out with damon yet, but i have to say he was the relaxed one on set and tried to make up for whatever neurotic energy his twin brought to the table. he's had a more successful career which makes him a touch more friendly and easy to get along with, but also opportunistic and arrogant! there was also a season (three, i believe?) that he missed the first 2 weeks of - he prioritized shooting the lighthouse which might've caused some tension on set. basically there's a lot to work with here but tell me what penny's like!
