The Schnee Co. people just give him her contact info to get in contact with her! Since she isn't usually in-office at Schnee Co. anymore because they're working on setting Winter in charge of the company while Weiss focuses on the GSRF. :) But they do mention that she tends to respond to any calls she receives, so it's best to talk to her directly.

They do give him the following information known regarding timelines/travel: It's unknown how people are physically brought to Genessia, but it is a very well known fact that peoples' memories can often vary from what the most current events in their world are. Additionally, it's known that the Dream Docks essentially "update" memories, but no one physically leaves Genessia while using them. This was tested using telepaths connecting to consenting individuals who were utilizing the Dream Docks.
