@mathnet: He killed himself by eating a poison-laced apple, and a story goes that this was the origin of Apple Computer's original rainbow-apple-with-a-bite logo.
The highlight of the episode, for me, was seeing Ianto's layabout brother-in-law round up the locals and charge the riot squad. I cheered.
I love it when a non-heroic character, who knows nothing of the big picture, decides to take a chance and do what he thinks is right.
@MsFeasance: My understanding is that the aliens have been doing everything for effect, to make the most dramatic impression possible. The squirming and spitting felt like it was put on for show.
@masterisosceles: Same here. I brought Tali along on every mission, not because she was terribly useful, but because I enjoyed her company and her banter with Wrex. They're the original odd couple!
