There needs to be some explanation why Pike doesn't do this in the alternate timeline though. Strictly speaking, realistically he should learn something in this week's time travel episode that his bad future counterpart didn't that saves Una from 7+ years of jail. What that could be, I couldn't really tell. The only wild card factor is James Kirk, who Pike is now aware of 7 years before they meet in the bad future timeline. Well, that and Pike now knows what Romulans look like years before anyone else in the Fed.
