Hundred Proof Star Trek (S5E12)

When some aliens with very upsetting temple loaf hitch a ride, Troi wakes up in a coma after one of them forces himself inside her mind. Unaware of the crime or its gravity, the crew tries to figure out what’s causing senior staff to slip into comas one by one. Is Riker really a horrible person? Did Marina Sirtis really punch that guy? It’s the episode that is almost impossible to make jokes about.
