Teddy and April discover that Laura's heart is spouting blood because a screw that came loose from her spinal fusion surgery is shredding it. Jackson is the one who performed the initial procedure while Callie supervised. Actually, she wasn't watching him all that closely. Callie tells Bailey that she was reading a magazine at the time. Now she has a first class case of the guilts.
Things go south during Henry's surgery. The laser option is out, so Richard takes over. But things go from bad to worse. Cristina can't understand why such extreme measures are being taken. There's no way they'll ever be able to get the heart beating again. The patient is gone and Cristina still has no idea it's Henry.
Shock and devastation set in the instant Owen gives Cristina the news. But he can't tell Teddy about Henry until she finishes the bypass on her patient. He knows she'll never forgive him for that. Richard says her husband died on their watch. She's never going to forgive any of them.
