IMO, the biggest problem in Arrow is that people don't tell each other things so that the person they don't tell doesn't come to harm, but the not telling ends up BEING the thing that causes harm. Over and Over and Over. You'd think that people would have learned by now! Communicate, dammit! (and oops, wrote this before I read your spoiler!) :)

That's totally fine, because I am pleased to know that this frustration is not just mine. :) There's a minor crossover in one Flash episode where Cisco and Joe West go to Starling City and meet Captain Lance during the time that Lance and Laurel are estranged because she lied about Sara's death; Joe asks Lance why his relationship with Laurel is strained, and Lance explains it's because Laurel lied about something important. I enjoyed watching Joe squirm a little -- because he's been so adamant that Iris not learn Barry's superhero identity, and it's SO OBVIOUS that Iris needs to know. (But of course Joe doesn't then immediately go home and tell her, sigh.)
