Talk about intensity. On 'Cold Case' (Sun., 9PM ET on CBS), Lilly tracked down her battered sister, only to find she wasn't alone. Yep, Lilly (Kathryn Morris) found out she was an aunt.

However, it wasn't all hugs and puppies after Lilly found the baby. Cliff returned and pulled a gun on Scotty, but Lilly was right behind him, and she was angry.

"How could you do that to my sister!?" Lilly screamed between blows to Cliff's head. She pulled a gun and then ... well, watch the video.
