I took too long to reply, but see GeneralChaos626’s reply.
That was what I was alluding to.
Improving the manor’s defenses is a step, but not the only step on getting Emma back.
Arc wouldn’t just hide Emma away willy-nilly to then give her back right away.
Similar concept to people asking for a healing spell for Gwen. Shit takes time, and “fixing” stuff right away makes “breaking” them in the first place completely pointless.
But yeah, we’ll get there eventually.
