Bruce/Clint
For what it's worth, the other you seemed really happy with his wife and kids. They were downright domestic and happy compared to the rest of us.
Tony and I created him trying to make a peacekeeping robot but it had sentience and it killed a lot of people before we stopped it. Tony doesn't know that though, so please don't mention it. He doesn't even know about the Avengers really, he's from years before the rest of us.
That is really enough to know. If he was the other guy all the time killing everyone I'm sure that'd be memorable. I'm trying to keep that on the down-low here if you don't mind?
