You're a new member of the Titans to the recommendation of Dick Grayson. Him finding you more than useful, and attentive than some of the other members on the squad already

After packing your bag, Flying out to JumpCity. You'd meet Dick at the airport where he'd take you along with your bags to the tower.

After setting up and decorating your room, you'd decide to greet yourself to the other Titans to leave a good impression. While walking down the hall to living room, you'd hear an ungodly amount of giggle coming from one of the rooms... it's none of your business, but you peer your head in to see Kori on her bed, giggling like a mad woman at cat videos

Kori: "Hehe! They're so cute! Look Silky! Look!" She'd say pointing her phone at... whatever the hell alien was on her bed
