I don't know, I just think it's a great sub-sub-subplot and also I like how often they just show her looking at him and you can tell she's just so Disappointed and/or Worried (and since I'm absolutely Shakarian trash, I eat that shit right up).

Also the scene where Garrus beats up Harkin really reminds me of the scene where Kenny beats up Carver and I live for my video game guys getting just a bit too close to the darkness, yes
