She just needs to stay dead. As much as I like her, the time warping shit from Rebels just ruined her and now Trace is going to tarnish her even more.
So wait there was water on Coursant the latest episode of Clone Wars. Did they reach the surface of the actual planet there?
In the EU they had a whole artificial sea on the top level, just for holidays and water sport activity. So I don’t think that 1313 is even deep enough for real surface water, probably only a canal or sewer drain.
