On Taris, Republic mission, the NPC Dr. Ryamn:
"I swear on my medical license. The real one!"
I like Dr. Ryamn (I think that's how his name is spelled). I wish he was a Companion. I'd trade in Dorne or Quinn for Dr. Ryamn as a healer/companion in a heartbeat.
I think pretty much everything M1-4X says is funny. Excellent voice acting, and dialog.
His "side missions" as his affection level grows are interesting, and often funny to me.
