The best people out of Ian's friend group are Emma and Jeremy both know what they want and who they are which makes it a rarity in both sides of the story because their motives are pretty upfront and they are certain about what they want.
I have to disagree on this with Emma. Emma is actually one of the worst friends to have. She is an activist not thinking five minutes into the future or about her friends. Look at the scene with Seymour., where she deliberately dumps beer over him, at a gig very important to Lena and the Cafe she works for.
Later she admits to have no evidence for her claims, just did it out of gut feeling. That Seymour probably has shady dealings is not the point, Emma would have attacked him no matter if guilty or innocent, just going by her beliefs!
To what end: Emma got Lena and the van Dykes into hot water with an influential man and patron! And it is clear by implication that Emma will continue to do so, no matter the innocense of the person or what Flak her friends catch. For ORS Seymour is written as a corruptor/antagonist, so Emma stays somewhat sympathical, but think about it if the person in Emma´s crosshairs IS innocent and there will be enough of them over time!
So Emma can go frak herself as far as friends go, IMO! You do not need friends who will pull you into any crap as a collateral just because they have a feeling!
