Vertigo was a fast paced action packed episode of Arrow. I really enjoyed watching because I was over deals with the Russian mob in order to find The Count who is the creator and dealer of the drug vertigo. It was awesome to watch Oliver do whatever he could in order to help his sister. Thea learns the truth about her mother and father after facing some serious charges. It was cool to meet 1 of Oliver's old friends on the police force. John is an awesome partner in fighting the good fight and he really took good care of Oliver. felicity connects with Oliver discreetly to tell him about something she discovered. There was lots of great character development and growth. I liked how everything played out and I certainly look forward to watching what happens next!!!!!!!!!
