[Spoilers?] If Barry faces off with Wells..

If The Flash faces off with Reverse Flash next episode, with the help of Oliver and Ronnie, does that mean he won't go missing, the article from the future will change, we won't see Hawkgirl and Iris Allen-West won't happen? Interested as this showdown is happening earlier than the future newspaper dated it to happen.

Also is the Queen Inc - Bruce Tech merge just there as a Easter egg from the comics? Would have loved a Batman equivalent live action on Netflix (so it can be dark without restrictions) crossing over with Arrow/Flash in the future. Here's hoping we at least get Green Lantern at some stage.
