Thank you! I know a lot of folks are riffing on this theme, but I did want to add a variation of my own. Depression can manifest in diverse ways, and--at least in my experience--it can be extremely insidious in its subtlety at times, especially if you haven't identified it yet.

I don't know if we'll ever learn much about Eli. On one hand, he doesn't matter (not in the Burt sense, in the narrative sense) because we're more concerned about what brought Blaine to that place and how he (& Kurt) may or may not recover. At the same time, I'd like him to be acknowledged as more than a literally faceless device.
