The Count was worse than dead the last time Oliver Queen saw him. But he is back doing his old nasty business and puts John Diggle (David Ramsey) and Felicity Smoak (Emily Bett Rickards) in danger.

The episode synopsis for Arrow 2x07 on TV.com reads:

"A deadly illness sweeps through Starling City. When Diggle is struck down, Oliver confirms that the source of the illness is a new version of Vertigo. Tracking down a lead, Felicity is soon captured by The Count, who has escaped prison. Meanwhile, Moira Queen (Susanna Thompson) fights for her life in the courtroom against a death sentence, and Laurel Lance (Katie Cassidy) is forced to prosecute her when DA Donner (Dylan Bruce) is stricken down by the same illness."

Things are very bad for Oliver Queen and his loved ones in Arrow Season 2, Episode 7. His friends are being attacked by The Count. And the love of his life is fighting for the state against his mother - for a death sentence!

Stephen Amell teases fans on social networks again. This episode is a must-see this AmellWednesdays on The CW. This is how Amell promoted Arrow 2x07 on Twitter:

Please watch the #arrow television program tonight because HOLY SHIT this episode.

"Gabel's back! I missed you. You evil bastard," Amell also tweeted, referring to The Count actor, Seth Gabel.

So far in Arrow Season 2, Oliver Queen, now known as simply Arrow, has helped Black Canary (Caity Lotz) reunite with her dad. The viewers get flashbacks of what else happened to Oliver on the island and how he and Sara Lance have crossed paths post the Gambit's tragedy.

Moving forward, more DC characters will be introduced in Arrow Season 2. Barry Allen aka The Flash will have a traditional pilot instead of a backdoor launch in the series. But Stephen Amell says Grant Gustin "did a phenomenal job" in Arrow Season 2 Episodes 8 and 9.
