All right Transplant, you have some explaining to do. We’ve been waiting all week to find out why the unflappable Bishop (John Hannah) had a moment of confusion that resulted in injuring a patient on the operating table! Luckily, this episode (which is also the season finale *sniffle*) picks up right where we left off, with Bash (Hamza Haq) and Claire (Torri Higginson) trying to figure out what’s going on with the ever tight-lipped doctor.Ever since the very first episode, when Bash used an electric drill to bore a hole in Bishop’s head to clear the epidural hematoma, Bishop has occasionally suffered from nausea and headaches. Claire (who recently rekindled her romance with the fine, gray-haired Scot) has noticed him intentionally down-playing his symptoms, and corners him in his office to confront him. When he admits his vision is deteriorating, Claire asks, taking his hand in hers, “You promised us a future. Did you mean it?”  That outpouring of love prompts Bishop to finally seek further tests, but it may be too little too late.

Please, get it right

As Bash suffers the consequences of accidentally nicking a patient’s spleen under Bishop’s observation, Bishop comforts him by saying, “We get it wrong until we get it right. Then we get to start over.” Those prophetic words will inform everything that befalls the York Memorial Hospital crew over the course the next hour, because Bishop suddenly collapses right in front of Bash and goes into cardiac arrest.Lightning-quick, before anyone knows what's happening, Bash is straddling Bishop, performing CPR as the entire hospital staff rallies around their beloved ER leader to save his life. As the crew realizes that Bishop is probably having a stroke from an undiagnosed ruptured aneurysm from his previous head injury, Bash flashes back to Syria again.For most of the course of this season, Bash has been haunted by images of what he experienced during the Syrian civil conflict—most notably, finding his mother’s lifeless body on the floor of a hospital, surrounded by partisan Syrian sharpshooters. Luckily, back in the present, he’s able to focus long enough to defibrillate Bishop back to life, but Bash is traumatized by what he’s just witnessed, coupled by what’s haunting him.As Claire sits by Bishop’s bedside, holding his hand, waiting for him to wake up, Bash retreats to the locker room in tears. Mags (Laurence Leboeuf), who has been his champion since day one, comes to comfort him with a hug, and something passes between them we haven’t seen before. They look at each other in a new way. There is some longing and affection there. Okay, we’re calling it. Bash and Mags love each other. Fine, it’s still early days for them, but just let us have this! W ho else loves the idea of them together?

Flashing back and starting over

Unfortunately, Bash’s flashbacks aren’t stopped by this newfound affection, and we finally see the full picture of that harrowing scene in the Aleppo hospital. On top of finding his mother’s dead body, he also found his wounded father, close to death. The troops were close to finding them while shots rang out all around and as Bash tries to gather his father in his arms to save him, his father protests. As we transition from the disturbing scene back to Bash sitting by Bishop’s bedside in Toronto, we learn the full extent of what Bash and his sister Amira (Sirena Gulamgaus) lost. “If I stayed to treat him, they would have found us. If I tried to move him, they would have heard us. So I left him to die. It’s my fault,” he cries. “It’s all my fault.”At that moment, Bishop wakes. Phew! We thought we'd lost him.
