Vince Adams's Links
Vince has basically been in love with Diana since they first met in the Lost MC. He never told her his feelings, however, due to her already struggling with her relationship with Tyler and feelings for Liz. He's content to be beside her for now, though who’s to say what will happen in the future.
Diana has primarily only seen Vince as a friend for the last X years. There may have been something poking at the back of her mind during their Lost years but it never had a chance to really come out. In the present day, however, she's beginning to realize she does have feelings for him.
Mateo is Vince’s best friend and has been for many years. He doesn’t have any secrets from Mateo, as Mateo’s the person he goes to for advice about anything. Mateo balances him out a little, keeping his reckless behavior to a minimum when need be.
Friends by way of Mateo initially. Vince may have held a grudge against her leaving the way she did, but nowadays they’re on good terms. They spar frequently as a hobby, and they feed off of each other’s high energy (especially during heists).
