On the B Positive episode “Die Alysis,” Drew’s (Thomas Middleditch) condition worsens and he (reasonably) doubts the responsibility of his kidney donor, former high school classmate Gina (Broadway star Annaleigh Ashford). When he visits her place of work, a retirement home, he meets one of the residents, Norma, who’s portrayed by triple-threat Linda Lavin.
