Clark discovers the Green Arrow was shot while trying to save a couple from a carjacking, but Oliver denies he was injured. However, when Oliver starts displaying erratic behavior, Clark and Chloe investigate and discover he is taking a super-drug that causes his body to heal itself but has severe side effects. Meanwhile, Lana makes a shocking discovery that will impact her relationship with Lex. This was a pretty decent episode that was obviously the show's Thanksgiving episode. Thankfully, (no pun intended), it was used as a backdrop.
