And now Ruiko is in a conundrum, isn't she? Side with Nova and potentially get natural Esper powers without the Level Upper (And without the mental side effects that come from being a psyker in WH40K, presumably), or side with the Ethereal because he has Mikoto with him. Decisions, decisions....

Depending on the outcome, the Ethereal might remind how much the righteous 'good side' has been beneficial to her. Also that Nova has already failed in his previous endeavor. 

Also Mikasa yah.
