'Believe' episode 3 pics: 'Origin' reveals Bo's powers run in the family

Through the first two episodes of "Believe,"viewers have seen some of Bo's (Johnny Sequoyah) powers and been told that she may have even greater untapped abilities. What hasn't been explored, though, is the source of her abilities.

That will change with Sunday's (March 23) episode, "Origin." Flashbacks will feature Bo's mother, Nina (guest star Ella Rae Peck), and Zap2ithas a few exclusive photos that help explain Bo's present-day story.

Nina was an original recruit of the group known as Orchestra, and as you can see, she got to know both Winter (Delroy Lindo) and Skouras (Kyle MacLachlan) in her time there. She has some of the same gifts as Bo and becomes pregnant during her time with Orchestra, which helps explain how Bo is on Winter's and Skouras' radar in the present.

When Nina's powers are used for military purposes and things go awry, though, she extracts a promise from Winter -- presumably not to let Bo suffer the same fate she has.

In the present day in "Origin," Bo and Tate (Jake McLauglin) are stuck in Manhattan and run across a woman (Shohreh Aghdashloo) still in mourning over the death of her son years ago. "Believe" airs at 9 p.m. ET/PT Sunday on NBC.
