Basically when Eobard first time-traveled to 2016 he learned many things: The Flash's time era/period, S.T.A.R. Labs, Harrison Wells, Joe, Caitlin, and Cisco.
2:00 - Man, these two remind me of DMC Dante and Vergil. They'll never accept each other, may occasionally banter while killing each other, but on every rare or so occasion, their teamwork is flawless
This thawne is a younger earlier version of thawne before he murders wells and kills Nora Allen and finds out Barry’s identity and timeline ! This is his first time he’s time traveled and finds out about star labs and team flash ! He already knows what time period Barry is from and thawne knows he has to be the reverse of Barry
Too bad this is the last time we will witness Eobard interacting with Harrison Wells... I won't count the deleted scene since Thawne was disguised as Wells when he tried to kill Harry Wells.
Almost. After this encounter, there are multiple showdowns between Flash and Reverse-Flash, but the most important one is this : Crisis on Infinite Earths. After this, Crisis occurs in 2024, Flash and Reverse-Flash went back in time as the aftermath of the original Crisis, thus leading to Nora's death that became a fixed point in this timeline, which has already been changed.
