I am romantically involved with Alistair, and for funnsies I decided to see what would happen if I broke it off. Saved first of course. When I talked to him I asked about him being able to teach others to be Templars and a little message popped up that said Templar unlocked, but I'm a Mage. What's going on?
Templar is now unlocked for all warriors. Other warriors in your team can now pcik that specialisation and you will be able to pick it if you do another playthrough with a warrior class (As long as its on the same profile)
