So my mother's making her way through the first season, and it's gotten me wondering: Eobard Thawne only moved up the particle accelerator explosion by five years, right? Was that really worth 15 years of effort masquerading as Wells? With all his science know-how and powers, wouldn't he have had more fun becoming rich and sipping piña coladas with beautiful women in Aruba all that time? What was so great about his future that he wanted so badly to get back there, anyway? And was someone who looked suspiciously like Harrison Wells racking up huge escort service tabs in Coast City all those years when Barry was learning high-school physics?
What part of irrational psychopath do you not get?
Earlier there was an allusion that Barry "caused" the death of someone Thawne loved.
It was a line like "you know what you did".
Maybe his child died, or maybe this is all because Barry splashed him with puddle water from a gutter and got his suit wet?
An element of "regular" sex is to reach peak levels, or at the least to increase your heart rate. That's not going to happen with a speedster boning at regular human speed. Which means that Eobard learnt tantric sex, or he melts and vaporizes women with his speed-dong.
Maybe he's got family in the future?
Although consider how we saw Thawne a couple weeks back on his way to kill Barry's mother, and he Knows NOTHING about a century ago that Gideon, a computer program invented and built by Barry Allen tells him is the "real" past, it's more than possible that Gideon is telling Thawne about a fantasy timeline that doesn't exist. This would mean that Thawne was living up to history and changing nothing, and the particle accelerator is always built when it's built because the Reverse Flash always kills Harrison Wells and there is no original time line where the accelerator is built 5 years later upstream.
