( This is basically a sort of Marvel's Runaways AU. Thad basically acting like Alex Wilder. In this AU Wells is Thad's last name. It's confusing for anyone who hasn't watched The Flash but it's the last name of the man the Reverse Flash killed, replaced and impersonated. For anyone not familial I'll keep both parts vague but if you know it I'll be more clear, )
Thad's father worked closely with your parents\parent being business partners, friends of your family since just before you were born. You knew Thad your entire life. You were raised in a loving, comforting home naive to who they really were. But Thad one of your oldest friends, wasn't happy you knew his home wasn't as good, it was colder, harsher and lately he seemed distant distracted.
On the same night you invited him over to talk about it, the two of you stumbled upon the secrets involving both of your parents\parent. They were cold blooded people who sacrificed others for years in return for more power, for complete control of the city because of a deal they made before you were born. The two of you ran away together, failing to notify the police, or have anyone intervene. Thad proposed the two of you could try and atone for everything they did. Along the way the two of you were framed, as you trained. Potentially uncovering abilities or skills of your on or just relying on skills and weapons. It seemed odd that Thad mastered his gifts before you did, like he knew longer.
Finally the two of you stopped their plan, when they were close to their reward for every awful thing they did in service of something ancient and otherworldly. Fighting them but then came things no one expected. Thad killing his father without a second thought. Thad had confessed earlier on how he hated his father, how he knew the man never cared. And the bombshells.
" Everything according to plan. I've known for nearly a year, I've wanted to hurt him for so much longer. We didn't stumble upon their secret, I led you here.. And I knew you wouldn't want to live in a world where your parents changed it with innocent blood... Running away provided the chance to be stronger, to distract them.. I lead you here for this.. Every resource they had,,all the power we have ourselves and their little deal.. We can make our own! What we've wanted, desire, we could make a new world practically." He offered putting his hand out.
