NGTV Guide: Tuesday, May 12

Fringe‘s first season finale leaves a lot of loose ends while The Mentalist and Cupid try to tie things up before their finales next week.

The Mentalist – CBS 9/8c
“Blood Brothers” – The team investigates the death of a student in a wilderness program of troubled youths.

Fringe – FOX 9/8c
“There’s More Than One of Everything” – The first season finale features the appearance of William Bell (aka Leonard Nimoy), the disappearance of Walter, and the reappearance of David Robert Jones. That should give us plenty to ponder over the summer.

Cupid – ABC 10/9c
“Left of the Dial” – Trevor’s latest match involves a radio DJ and one of his listeners, while Claire seems to be making her own match with the statistician helping her develop an eHarmony-like questionnaire to match people based on commonalities. Which will bother Trevor more: a man moving in on Claire, or a man moving in on his matchmaking abilities?
