so first, he would definitely help any of his family members who are being captured, I would like him to be a part of Irene's plot. Dont mess with the fam.
And as for his demonic outbursts, when they do happen they are rare but they are catastrophic. He also doesnt look to closely like his "regular" self and can be mistaken for something else. He is very manic as a demon so he will chaotically ruin and break anything around him. That being said family members can also fall prey to these kind of outbursts.
Seiichi almost received an attack and was chased before leaving Solaris.
Suji is ironically so concerned about he is trying to figure it out himself, instead of asking for help, he is worried about a negative result if he asks for it [help], and not just the family being displeased, he is worried he will have an outburst at the time should he ask for help.
He thinks he can keep it under control, meander off when he thinks it's about to happen. But that's not always going to work out.
Maybe one of his outbursts can happen when the fam tries to save Irene's babies? Or we can plot something else
