Sonequa Martin-Green puts on an acting clinic in the latest Star Trek Discovery episode "Perpetual Infinity," all while Michael Burnham is working through some serious mom issues. 

Alan Van Sprang's Leland kinda recovers from getting stabbed in the eyes last week, and gets to paying the stabbing thing forward to Ash Tyler. 

Sonja Sohn gets a lot of screen time in this episode as Michael Burnham's mother, and hot damn is she stupendous. Competing for that maternal role is Michelle Yeoh as Mirror Georgiou.
