I probably shouldn't be so giddy by this women's death, right? Oops. I feel nothing but enjoyment. Bye Dr. Tsing!
Loving the former president realizing how bad this is and being willing to help Bellamy harm (or kill) his own people to help allow the 47 to escape.
Also, Raven for the win. Getting Bellamy mobile on that radio was so important (and probably impressive, I don't know anything about technology). Plus, it literally saved Clarke and a bunch of other people at Tondc.
Bellamy is totally gonna go back and save all those Grounders, right?
Plus, if this bone marrow transfusion works so well, and within 48 hours, why didn't Dr. Tsing just inject herself? Not that I'm complaining, I'm thrilled she's dead, but she totally seems like the person so save herself first.
