'Sleepy Hollow' Season 2 Spoilers, Plot News: Buffy's Michelle Trachtenberg To Play Abigail Adams

With the help of three people, Michelle Trachtenberg has finally been able to squeeze herself in Abigail Adam's corset to play the second First Lady of America on "Sleepy Hollow."

Trachtenberg joined Monday's episode of the supernatural drama series as founding mother Abigail Adams, the wife of second American President John Adams and mother of another U.S. President, John Quincy Adams.

"My pale skin sort of lends itself to the era," the "Buffy: The Vampire Slayer" veteran quipped in an interview with the Entertainment Weekly.

Trachtenberg's character was "as historically accurate as possible, with a little twist: She is trying to catch the big bad evil that is ruining her era and becomes a profiler of sorts."

in typical Sleepy fashion, Hollow fans will learn that Abigail had a secret life that involved Katrina Crane, who helped her out in a fight.

"I would like to say that they're sort of a Sherlock and Watson combo. Abigail Adams, because of her power and her wealth and her outreach in the community, would probably be Sherlock, and she looks to Katrina to aid her in her hypotheses," Trachtenberg said, according to TV Line.

"I think when you have an amazing talent like witchcraft, why not use it? ... It is a physical being, which is something that you technically have to say when dealing with Sleepy Hollow. It is someone that can travel from then and now, and someone that seemingly is captured and their intentions destroyed, but ... evil has a way of magically reappearing," she added.

Trachtenberg -- who had colorful stints on Gossip Girl, Weeds, Criminal Minds and NCIS: Los Angeles -- also revealed that it's "very possible" that her character could return as discussed by executive producer Len Wiseman.

"He and his wife are very close friends of mine and that's actually how this all sort of came to fruition, and how I had started watching the show in its first season," Trachtenberg said.

"I couldn't keep on watching every episode, because I live alone, and I have an overactive imagination, and I'm convinced that there are things in the shadows," she added.

Trachtenberg also shared thoughts about her longest hair and makeup process, which actually took three women to lace her into her corset.

But don't think Abigail Adams would let a little thing like breathing stop her in the fight against evil.
