basically the way they've said it'll play out is that this paramedic guy is Doomsday and his story will unfold over the season. so far he's just been a nice guy friend but tonight they started to reveal the darker aspects.
Clark was up late at the Daily Planet listening to the police scanner and super speeding around the city stopping crimes when he heard about some violence at a night club. he gets there and it's a bloody carnage. the survivors describe only some guy with bones sticking out of his body. the paramedic is found by Clark under some debris covered in blood, but it turns out not to be his own blood.
Martian Manhunter has taken the John Jones identity and managed to get a detective rank with the Metropolis PD to help Clark and they investigate the murders. Meanwhile the paramedic (i forget his name and just think of him as Doomsday) confides to Chloe that he has blackouts and they've been getting worse, and Clark confronts him about how he always is the first responder on scene but the paramedic turns it around and points out how in the initial crime scene photos Clark is often there when there is no way any reporter could get there so quickly.
Turns out there's some shadow villain guy who killed a few people, is captured, and confesses to all the killings but at the end they mention a necklace from one of the victims that is missing and wasn't in the shadow guy's apartment and they show it in the paramedic's car.
it could turn out to be a pretty good storyline afterall. But they need to ditch Green Arrow and Tess who weren't in this episode and it was the best so far this season.
