NGTV Guide: Thursday, May 20

It’s a trio of season finales tonight as Bones, Fringe, and The Mentalist pack it up – and most likely leave us hanging – for the summer.

Bones – FOX 8/7c – SEASON FINALE
“The Beginning in the End” – The team works to uncover clues buried under a life’s worth of possessions saved by a hoarder in order to solve the mystery of his death. Meanwhile, Angela’s father (guest star Gibbons) has a specific purpose for his most recent visit, and Brennan and Booth are confronted with unique opportunities.

Fringe – FOX 9/8c – SEASON FINALE
“Over There, Part 2” – In the second part of the two-part season finale, sacrifices will be made and both universes may never be the same again after Walter and Olivia visit the “other side”.

The Mentalist – CBS 10/9c – SEASON FINALE
“Red Sky in the Morning” – Patrick Jane and Kristina’s first date is interrupted by a report of Red John striking again, which is discovered to be a copycat.  But when Kristina reaches out to the real Red John, both she and Jane find themselves in grave danger.
