HI! I have a dumb question but how do you start Garrett romance after you get 100/100 of his friendship? I'm having trouble, sorry.
Advance through the bear fist tournament (After some fights, you'll have a special training event. There you'll be able to start the romance). One note: if you started Dalton's romance previously, the game will not allow you to romance Garrett. Check the bear fist tournament section of the help section for more details
