Warning! Do not proceed of you are not all caught up with iZombie!

Last season of iZombie ended on a crazy note. Ravi (Rahul Kohli) created one dose of a zombie vaccine, and he asked his best friend Liv (Rose McIver) to do the honors of scratching him. Zombies are out of the closet, after Chase reluctantly goes through with “Plan B,” infecting half of Seattle with a vaccine that was really the virus.

Last week on Arrow, the team disappeared one by one, courtesy of madman Adrian Chase and Black Siren (Josh Segarra, Katie Cassidy).

Merlyn (John Barrowman) joined Oliver to save Thea (Willa Holland). Loyal Nyssa (Katrina Law) joined despite hating Merlyn.

Last week’s Flash was full of tears, as Barry (Grant Gustin), desperate to save Iris (Candice Patton) as the clock wound down, went back in time to get Captain Cold (Wentworth Miller) to help him steal an energy source from A.R.G.U.S. This energy was needed to fuel the “speedforce bazooka” that Tracy Brand (Anne Dudek) built, inspired by her muse and crush HR (Tom Cavanagh). After a harrowing reenactment of Jaws, they retrieved it and Barry and Snart said goodbye in a bittersweet moment for Captain Cold fans. The team went to Infantino Street to stop Savitar from killing Iris, but it didn’t work. Savitar ran Iris through and Barry held her body in his arms. Vibe (Carlos Valdes) and Killer Frost (Danielle Panabaker) faced off.

Last time on Supernatural, hunters were being taken out – Eileen (Shoshannah Stern) got killed by a hellhound. Mary (Samantha Smith) dreamt she killed a hunter, but it wasn’t a dream. The British Men of Letters and Lady Bevell (Elizabeth Blackmore) were brainwashing her. Sam and Dean (Jared Padalecki, Jensen Ackles) got the best of Bevell, but then Ketch (David Haydn-Jones) came and entombed all 3 of them in the bunker to die, with brainwashed Mary’s help. The power started to reverse between Crowley and Lucifer (Mark Sheppard, Mark Pellegrino), until Lucifer broke free and gleefully killed Crowley.
