Well, at least H/Dalki Hilston doesn't want Sil body anymore, which isn't a bad thing, although I'm interested to see what Sil is planning. I love how Minny just stepped in again to save her uncle Sil, and is even ready to work as his shield, giving him a fighting chance. I am a little concern that this fight could well be Sil last, forcing him to sacrifice everything to take down H, but if that happens, I hope that the healers from before/Vicky/Shiro jump in to help him.
So it will either be the memory ability or mind ability maybe both. Either way this is a way for Sil to win in his current state assuming that H doesn't have a countermeasure for mental abilities in case Jim tried to turn him. Neither Truedream nor Jim trust each other so they likely have counters set up in case the other turns on them.
