Steve is checking himself in for three weeks of treatment. He didn't say exactly what he's been treated for, but he mentioned a bit later that he's been using drugs.

I'm not surprised. Since he returned to Seattle, I've noticed a weird paranoid streak running through him. He's obsessed with the idea that someone has been hacking his phone and computers. Because I'm tech savvy, it was possible that I was the one doing that, so he never trusted me enough to share the details.

A while back RO speculated that Steven's been using meth. He guessed this because Steve has developed a jaw grinding habit that he's only ever seen in other meth users.

I wish him well. It's frustrating to see this. Ten years ago he was a role model for me. He had a strong career, a great partner. He knew how to get a lot out of life, yet still be at the top of his game at work. He still has the energy and is still very bright. He just gone off into the weeds.
