I'm not really getting into Season 2, end of season one he says "I was the one that sent you back, and you'll never believe why" and when we they showed us the message it made no damn sense.
2077... my time, my city, my family. When terrorists killed thousands of innocents, they were condemned to die. They had other plans. A time travel device sent us all back 65 years. I want to get home. But I can't be sure what I will return to if history is changed. Their plan: to corrupt and control the present in order to win the future. What they didn't plan on... was me.
