* PowerWalk: Si-ohn and the cops accompanying her indulge in this when they walk into a meeting in Episode 15 and arrest Hong Joo, the crime kingpin.

* WitchDoctor: Si-ohn visits Hee-bin, a shaman who says that "resentment" is what drives the ghosts to appear, and suggests that Si-ohn sees them because she wants to see them. This being a KoreanDrama, Hee-bin is not some wizened old person but a hot young lady who likes to go dancing in clubs. Further episode reveal that while Si-ohn can see ghosts, Hee-bin can talk to them as well.

** Hong Joo, who ordered the hit on Woo-chul, later orders Park Il-doo to be eliminated for this same reason. This backfires as the hitman doesn't finish Il-doo off--he is scared away by a passer-by--and Il-doo winds up informing against him.

** Gun-woo's jovial, fatherly mentor, Moon-shik, is revealed to be in league with the smugglers. He is also the person who shot and killed Si-ohn's boyfriend Hyung-joon, although he didn't mean to. After Hyung-joon was cornered by the smugglers, Moon-shik shot him square in the chest, thinking he was still wearing his bulletproof vest for the stakeout. But Si-ohn had arrived at the stakeout earlier, and had Hyung-joon take off his vest to try on a new shirt she bought him.

It turns out the Lost and Found Center isn't light duty after all, because of one thing: Shi-ohn now sees ghosts. Six years being sort-of-dead has now caused her to see spirits, including the spirits of people associated with items in the Lost and Found storage. The ghosts that she sees are people who were the victims of foul play, and Shi-ohn, with the help of the ghosts, starts solving cold cases. She also gets assistance from another ghost--Hyung-joon.
