A really cute teleport. Neat that lead blocks her power so covering her in lead paint prevents her from teleporting - just as covering the Invisible Man in paint makes him visible. Clark can throw it at her so fast that she does not have time to teleport.
Good to see Luthorcorp and Lionel again. An elevator would not drop in the Luthorcorp building. The connection between Adam and Lionel is revealed but the truth still comes out in very small doses.
Pete says, "We've had our problems lately," referring to the way things were between him and Clark at the end of the previous episode. Clark not being honest with Lana makes less and less sense - but it is necessary for the story.
