Ellie and Saren actually spend time with hacking programs in a friendly competition of who can get through encryption faster and more efficiently than the other. It’s not really a mother/son thing that typical families do, but Ellie is trying to bond with an adult son that she doesn’t share a whole lot in common with merely because he hasn’t really shown any interest outside of work. Everyone who cares about Saren are trying their damnest to open him up and show him life is more than just work, but it takes time. (hint: It’ll happen more in Efflux ;))
Garrus and Cassia actually spend a lot of time together. Since she was a kid, she shared a lot more in common with her dad than mom. Not that she doesn’t get along with Jane and have things they share, but just that she shares interests with Garrus more. He likes to build things and she built a knack for it over time, so when they’re together, they are often working on something. I’m sure he’s probably picked up a sand buggie or two to work on with her. If that’s not around, sometimes they just like to sit out in the sun and read. That’s Cassia’s favorite.
Haha, that last question.
Yes, James and Sol have had sex where Garrus was all too aware that’s what they were doing. In fact, it’s happened more than once. Thankfully he didn’t walk into it or anything, but more than likely smelled the two of them just before they make it obvious they were leaving the room to do the do. He wouldn’t act like a human would at seeing his sister having sex, oh no. More like he’d be exasperated that they had to do it where he was going to walk in.
G: ‘Seriously? Don’t you lock your front door? I’m not using that couch until I see you clean it off’
Thanks for the asks!
