From what I heard he left the ceremony shortly after the incident. I do agree that he should try to apologize to them, but I think in the moment all the shame and embarrassment understandably got to him, and he ran away so as not to cause more disturbance in the moment.
Meanwhile Michael B Jordan and Lindo would've been on stage and then back in their seats in the auditorium. I suppose the guy with tourettes could've waited until afterwards to find them.
