EJ

Never heard of Trey B, but I’ll have a hard time accepting anyone else as EJ.

James Scott has been quoted as saying that he wanted to do other things with his life rather than being an actor.  He appeared on DOOL 2006-2014.  He appeared in the pilot episode of TV’s Private Eyes in 2015 and in the pilot episode of Wrecked in 2016. No acting jobs since then.  The following explanation is on Wikipedia.

During an interview in April 2014, Scott described a spiritual experience he had in Peru during a trip to the country, from which he had just returned prior to the interview – and during which he took Ayahuasca with the guidance of Native Peruvian shamans. During the interview, Scott described the experience as "the single most positive experience of my life" and further stated of the experience that "it sounds wacky when you say it, but it was truly the most important thing I have ever done. I came back a very different person." 

Ayahuasca is an entheogenic brew made out of Banisteriopsis caapi vine and other ingredients. The brew is used as a traditional spiritual medicine in ceremonies among the indigenous peoples of the Amazon basin and is known by a number of different names.
