Fan Casting Dr. Niles Caulder in Titans

A few days after the last events, someone knocks on the entrance door of the Titans Tower, causing Beast Boy to open it, to his surprise, to the one who was practically his adoptive father, in the form of Doctor Caulder. The other Titans had previously arranged with Niles to make a surprise for Logan, as a way to celebrate his birthday, where he appears accompanied by the other members of the boy's old team of heroes, the Doom Patrol. Before the screen fades to black, the smiling Beast Boy can be seen blowing out the candles on his cake, alongside his large family.
