Twitter/nbcdaysSteve and Kayla race against time as Steve's condition worsens.

In the upcoming episodes of "Days of Our Lives" from Feb. 12 to 16, a lot of interesting revelations will happen. Among these is Kate (Lauren Koslow) and Billie's (Lisa Rinna) sudden reunion, with the latter having unknown motive for coming back to town.

In an interview with Soap Opera Digest, as reported by Soaps She Knows, head writer Ron Carlivati revealed that Billie has her set of mysterious reasons for coming back to Salem. He further shared that her motives are related to John (Drake Hogestyn) and Steve's (Stephen Nichols) story. The 49-year old writer even shared that Billie's comeback has something to do with exposing John's actions toward Steve. On the other hand, Soap Hub labelled Billie's return as something "twisted."

Other stories set to happen this week include Kate discovering something interesting at the DiMera Mausoleum; JJ (Casey Moss) confronting Lani about a very important matter; Billie saving John's life; and Eric (Jensen Ackles) finding out that he only had a misunderstanding with Jennifer (Melissa Reeves) and asking her if he could have another chance. On the other hand, Marlena (Deidre Hall) will be questioning John's behavior.

Also featured within the week is Hope's (Kristian Alfonso) curiosity about Carrie's (Christy Clark) reaction toward her and Rafe's (Galen Gering) wedding invitation. The couple would also be seen getting some day off at Smith Island to spend a romantic vacation. Back to John and Steve, the former would be injecting another dose of medicine to the latter while he finds something unusual in his hospital bed.

In terms of celebrations, Eli (Lamon Archey) and Gabi (Camila Ganus) will join in the celebration of JJ and Lani's engagement, while Abi and Stefan will have some moment to talk about something.

"Days of Our Lives" airs weekdays at 1 p.m. EST on NBC.
