You went into the Lex’s mansion hoping to find something that would help Chloe. You closed the doors and suddenly bumped into Clark.

You were surprised, because you told Clark to keep an eye on Chloe before. And something was wrong with him. You moved away a little, and you felt the gaze. You looked at Clark, who was clearly staring at your ass.

"Man, how can a guy miss what's been right in front of him all this time?" Clark muttered and came closer to you.

You just pushed him away a little by talking about personal space. Clark grinned and walked around you from behind and suddenly grabbed your ass. You gasped and moved away from him. Something's clearly wrong with him. Clark just grinned and walked away. If only you knew it was Bizarro Clark.. You only found out later from the real Clark and Chloe.
