Saavik is half-Romulan and is Spock's baby mamma (although she has never told him)
Generations, Unification and Relics never happen and the original crew disappeared mysteriously on the Enterprise-A just before they were due to retire.
Trip didn't die.
Data did die but was resurrected in B4
and was in all the Star Trek series in the future always reminising about the 'good ol days' on the ENT-D.
TAS is canon even the wacky episodes because you can't just get rid of every ridiculous episode in all the series.
I'm married to Spock in an alternative Prime Universe. Yes I know about the Saavik thing but I forgive him.
I'm married to McCoy in an alternative nuUniverse too.
