She got a mention a couple weeks ago but I didn't think it was more than an Easter egg. Is agent 33 a major player within SHIELD? The only info I found on her was that she appeared in a Hercules mini that's over 20 years old. Has she had any other notable appearances since then.
This was kind of a meh episode for me. Other than the May on May action, it was pretty much forgettable. At least Fitz is showing signs of progress.
