Cassie begins having nightmares and is stalked by the Nephelim, all the while she and Thelma search for the baby

Cassie attempts to steal her baby back from Azazeal, as Ella prepares for the ritual, and another sacrifice is made.

Ella toys with a boy to draw a seraph out, Roxanne continues with her plan of seduction, and Thelma negotiates with Azazeal.

Thelma's deal with Azazeal has tragic results for Ella.

With Ella declared a Section 2, Thelma turns to Leon for her rescue.

Ella gets sicker as mortality creeps up on her, and Malachi's behaviour concerns Azazeal.

Malachi begins to pursue Ella in earnest, Thelma gains a companion, and Leon makes a misstep.

Malachi's and Ella's feelings for each other cause physical problems, Leon plays it cool, and Thelma worries about a mark on Maya.

Ella has done a complete turn-about and is slavishly catering to Malachi who's exploring his newly discovered powers, and it's up to Leon again to save the day - unless Thelma gets in his way.

Malachi finds the source of his power, and Ella's means of diminishing it have repercussions for Thelma.

Malachi schemes to reach Leon and Tom, and Thelma's loss helps her choose sides.

The countdown begins to the end of days, and help comes from an unlikely source.
