McKay basically molesting the stasis pod was kind twitchy for me

It's really odd to me to see you say that, because it wasn't meant that way at all, more as him wanting to touch Sheppard because he's worried, and they haven't seen each other for twenty years, and so he's standing there with his hand on the pod because it's the closest he can get. Like all the cheesy movie shots of people touching their hands together through glass when they can't touch in reality for whatever reason.
