She's a beast. But all us locals have.
In regards to time? Going forward instead of backwards. We tend to not make huge changes in time as a rule but you all seem to go as often as you come so I imagine it would be a few years at best -, you never know what you might fuck up along the way. But there could be a possibility of manipulating how time perceives her going forward, negating the disappearing part. Less trying to go back and fix something that occurred outside Vallo and more changing how Vallo reacts to it going forward.
