Jesse Terr
"Spencey!! You're here. You've come home!" Joker exclaimed, running up to Spencer and hugging him tightly.
"Hello again, Kerr." Spencer said as he hugged him back.
"...Who exactly are you?" One of the other villains in the room asked.
"Dr Jesse Terr. At your service." Spencer mock bowed and Joker tugged on his waist.
"But... Mistah J just called you Spencey?" Harlequin
"...Jesse Terr. Jes Ter. Jester! You're the Jester!" Ivy exclaimed.
"Yep! My husband, the Jester!" Joker giggled, kissing Spencer. Their lips parted and their tongues tangled as they kissed.
"Husband?!" The BAU team exclaimed in shock, causing Joker and Spencer to pull apart.
"Really? That's what you're shocked about?!" Bruce Wayne asked, looking at the team as if they had an extra head.
"Pretty boy's smart. There was a small and I mean small chance he was a villain let alone a supervillain! But we didn't even know he was gay!"
"Pretty boy?" Joker asked, smiling at them sinisterly.
"Lay off, Jack." Spencer said, hitting Joker's arm that wrapped around his waist and pulling him back into his husband's chest;
"My name is Dr Spencer Reid-Napier. So yes. I have a husband. And yes, Derek. He is incredibly possessive."
