We now know Julian was a scum, so it'd be good to scrutinize their actions one more time.
Day 1: complete inaction (confirmed by being allegedly replaced by the organizator), this means whoever is an ice planet was acting alone on the first day and night. Not much information, but worth remembering. To me, that means that one ice planet scum was probably not as risky and spent the day rather passively, knowing full well their team is in a bad spot.
Day 2: Joon accused Julian to be a fire planet due to his low activity.
ClevelandsMyBro defended Julian and remarked how inactivity is more likely to indicate he's a townie. GamlA did not defend Julian, but asked about this accusation.
After a while ClevelandsMyBro decided to put suspicion on Julian as well (without voting however).
Julian defended himself and said he doesn't have a lot of free time currently, while proposing other options to who could be a scum. He also slightly accused GamIA of being a fire planet based on a post of IAVS. The latter to me speaks a lot, because his low activity does seem genuine and this accusation could spiral out of control very fast and put GamIA at a risk of being voted out. Not worth it, if he was his ice partner.
Night 2: Julian died.
