^ An eminently plausible timeline.
As an aside, I always liked how the writers made Q an unappreciated hero. The Borg were already in the Alpha Quadrant. Simply nobody knew about it. Had Q not sent the Enterprise to J25, humanity's subsequent encounter with the Borg might very well have resulted in the end of the Earth.
Agreed, that timeline makes a lot of sense.
Yeah, they owe 'Q' big for that one - always thought that.
But that seems to be his thing - unexpectedly showing up for what seems to be a benign situation, being obnoxious apparently for the heck of it, the situation suddenly turns out to be Not What It Seemed, yet everything (including Q being there) somehow turns out for the best anyhow, and for thanks Q then gets a lecture on how great we Humans are.
