While she has been doing her own fair share of scheming since returning to Salem, Kristen (Eileen Davidson) did appear to be somewhat changing her ways-but that's all about to end on Days of Our Lives.

Theresa Panics Over Kristen's News

While she has schemed quite a bit and refused to give over the second half of the drug that could potentially reverse John's (Drake Hogestyn) coma until she was promised that Eric (Greg Vaughan) would no longer testify against here (ensuring her freedom), Kristen appeared to making some changes and looked like she was trying to turn over a new leaf so she could win Brady (Eric Martsolff) back. However, after realizing Theresa (Jen Lilley) also wanted Brady, her dark side began to emerge some more-with threats on the younger girl's life. But now, after learning that Theresa had slept with her former fiancé since the threats were leveled against her-Kristen will snap.

When she does, she may inform Theresa that the drug was administered to John, and that he could wake up as a result any day now-which would make her the one Brady would want more, since she was the one who found the potentially life-saving procedure.

Brady Stuns Theresa With A Kiss

Unfortunately for Theresa, this news is terrible, and her nerves will show-revealing the truth to Kristen-Brady didn't attack his father in a drunken stupor and put him in the coma by hitting him with a fireplace poker-Theresa did.

Now, Kristen will try to figure out how to use this revelation to her advantage, and will likely warn Theresa that she is to never have contact with Brady again-or she'll tell him everything.

Days of Our Lives airs Monday-Friday at 1 p.m. on NBC.
