Latest "The Flash" season 2 spoiler says the next episode is basically second part of the two-episode big arc.
This greatly involves Earth-2 version of Harrison Wells who clearly is not welcome to most of members of the STAR Labs.
The last episode saw how douchebag of a person Harry can be. This does not help him in his cause to earn the trust of the Earth 1 people.
Except for Barry Allen (Grant Gustin) who felt a little excited about his arrival, everyone else hates him. In the next episode though according to recent "The Flash" season 2 spoiler, one unlikely STAR Labs crew will sympathize with him.
"The person with whom he ironically finds the most common ground with is Caitlin," EP Andrew Kreisberg said as quoted by Entertainment Weekly.
"There's a lot of stuff in upcoming episodes where there's a lot of hurt feelings, obviously on Barry's part, Joe's part and Cisco's part. We collectively decided that Caitlin would be the one who was able to - because Caitlin is more mature that everyone else there - both [see] the necessity for including him in things, and is also the one who has grown up enough that she can look past it and see that making a connection with him has value."
This connection is labeled unlikely because Caitlin Snow (Danielle Panabaker) is still very much hurt by the loss of her boyfriend Ronnie Raymond who vanished after saving Barry from the wormhole created after Harrison Wells/Eobard Thawne was erased from existence.
Earth 2 Harry, as Cisco calls him, is important to the team right now as he claims he was the one who created Zoom who is sending villains to Central City to kill the Flash.
Jay Garrick (Teddy Sears), Earth 2's The Flash, is there but there is not much he can do since his powers were taken way by Zoom.
Will Caitlin be the key for the new Harrison Wells to earn all of STAR Labs people's trust? Remember that according to Jay, he has a lot of secrets.
Show returns on November 10 for episode called "Enter Zoom." Read "The Flash" season 2 spoiler/synopsis below.
"After recent events, Barry decides it's time to confront Zoom and comes up with a dangerous plan. Caitlin sides with Jay and deems it too dangerous for Barry to engage with the speed demon. However, Iris (Candice Patton) shows her support and brings forth a surprising ally. We see what Earth-2 Harrison Wells' life was like before coming through the breach."
