Portrayed by Peter Krause, Bobby succumbed to a deadly virus after heroically giving the sole available antidote to his colleague, Chimney (Kenneth Choi), choosing to remain quarantined to prevent further spread. This selfless act concluded with an emotional farewell to his wife, Athena (Angela Bassett), and a poignant scene of Bobby collapsing in prayer.
