Thank you guys!
Will, I haven't repotted it. I don't have access to a new pot or soil, so it's not really an option. Also, unfortunately, there are no windows in my office. It's not in the dark completely though- the regular lights are on all the time as we have a night shift that comes in. I'm honestly proud of it for surviving at all. What you're saying about the leaf growth makes sense. When I took it, there was hardly any moisture in the pot at all, but now my well-meaning coworkers seem to water it every chance they get. I've moved it to my desk where I can shield it from too much love.
I'll definitely let you know how it progresses.
Thanks again!
