I'm totally down for friendships. Jonathan needs to get out more. He's turning into an introverted geek, needing someone to force him outside the apartment.
Depending on how close their friendship takes them, Brysen will know about Tybalt, who Jonathan has claimed as his Alpha. What isn't well known is that Tybalt is actually collared in a D/s relationship which they both take seriously, but are keeping under wraps. Another potential storyline for you there?
