You said our families would be told we were on a covert mission but not about the time travel? Because I think it would be better if I told Clint that part when I got back and he sees that I am back since the last time I went time traveling, I kind of died.
But I know the basics, don't interact with ourselves if we see us and don't mess up the timeline. I read the previous mission notes so I think I'm up to speed.
