10 Most Messed Up Deaths In Star Trek: The Next Generation
4. T-Cell Hack, Breaks The Ensign's Back — Ensign Dern
When the Captain's away, the progressively de-evolving crew will play… and kill. Don't forget kill! All it took was a teeny tiny synthetic T-cell sent to fight off Lieutenant Barclay's Urodelan flu for all aboard the Enterprise-D to turn to mayhem and murder in Genesis. With an arachnid, proto-hominid, and whatever Worf was, amongst others, roaming about, it's a wonder there weren't bodies lining the corridors. As it happened, there was only one confirmed death. Enter the introns; exit Ensign Dern.
Since everyone was going back to the wild ways, Dern's death was particularly savage. It's never stated who killed the conn officer, but proto-Riker was only in the other room! It would have had to be someone with the ancestral strength to break an upper spinal column "in three places," as per Data's in situ autopsy report. Just spitballin' here, but that also makes pure concentrate of Klingon, Worf, a suspect, too.
Not only did Doctor Crusher's hack lead to broken back, poor Ensign Dern, technically 'No Name,' unless you watch the end credits or read the script, also suffered severe lacerations to his chest and neck. By the 'I didn't sign up for this' look on his face, eyes wide-open in horror up to the ceiling, and the amount of blood, those wounds were made before death. His console hadn't done too well out of it either!
