[@Majoras End] Eliza is one of the two that it would make sense to be able to stumble across the Sanctuary, since she's been there before, so if my word has any say on it I say it's fine for that to happen.

I've also got no problem with there being another Robot waifu either, the Aigis/Metis type angle would be interesting to play around with if you wanted to do such. Especially as Aigis was at least partial used for inspiration for Penny.
