Another hint is how the witches explain how if he is to do anything about Satella's current situation he needs to become a Sage, having in his power most if not all witches genes, which is still a long way to go. Going into battle against one of the strongest characters in the series with only 2 authorities he can barely use would just get him killed fast You have to think about why Subaru has Return by Death in the first place that is the KEY to the whole novel . It comes from Envy there is no denying that, a Satella personality,  of all the places in that world, he is summoned at a location where Emilia will show up and the day she was to die by Elsa, hence Satella has some use for Emilia, not necessarily a vessel. but a way to release her . however as weak as Emilia is, she has no chance to survive the witch cult let alone reach the tower, which is where the second part of the plan comes in. Subaru with RbD is the only one that is able beat almost impossible odds, as long as the enemy doesn't know about it. One particular anime very recently exploited this ability is the "12 Zodiac War" that and the part that he has the same scent as Flugel and is from the same world tells me that either Flugel orchestrated his summon at this time or that Satella summoned him and it is for her benefit.
