In episode S3E22, Ray has Felicity sign some "corporate stuff" while talking to her. You'd expect her to actually read the document prior to signing it, since the last time someone of Team Arrow was in a rush and signed papers without reading them properly Ray's name ended up on the building. Sure, he's not a villain, but still.
This happens when Felicity is a bit distracted by other things, not noticing that it probably was something big. But what was the document she signed? I think it had something to do with corporate restructuring of Palmer Industries in Felicity's favor, but why did he do that?
Sure, the out of universe reason is likely that Ray is going to appear on Legends of Tomorrow and they need an excuse for him not showing up on Arrow anymore (or at least not as the Palmer Industries CEO), but I'm curious as to the in-universe reason.
