S2E5 A Night in Sickbay

Title: An Evening in the Infirmary Plot: Captain Archer finds himself staying overnight in sickbay alongside Dr. Phlox when Porthos falls victim to a lethal virus on the Kreetassan home planet. While the crew assumes that Archer’s heightened anxiety stems from his dog's condition, Dr. Phlox has a different theory, believing it relates more to Archer's bottled-up romantic feelings. As the night unfolds, tensions rise and personal revelations come to light, making for an unexpected evening of introspection and connection.
