She first came to town pretending to be Jason's (Billy Miller) wife, but was quickly revealed to be a fake. Not long after she was put in a coma after Nikolas (Tyler Christopher) had her shot. After waking up, she returned to his mansion, and the two quickly seemed to be falling in love--though Hayden has secretly been working for Tracy (Jane Elliott) to try and take ELQ back for the Quartermaines.

Now, Hayden has gone through with the next part of the plan needed to succeed for Tracy, and has officially married Nikolas in a ceremony in Las Vegas. However, after he left to go pay for their nuptials, someone from Hayden's past recognized her and called her by her real name--Rachel--and now she will need to do damage control to ensure this person doesn't spoil her cover in front of Nikolas.

Michael Easton Returning To 'General Hospital'

"I'm not who you think I am, do you understand?" She says in a preview clip for the Thursday, February 4 episode.

So far, she's managed to keep the truth about her real identity a secret from everyone--except for Tracy, who has been holding it against her as blackmail to go through with the scheme. And now, if this person recognizes her and blows her cover, not only will it destroy everything she has with Nikolas, but it will kill the plan with Tracy as well.

General Hospital airs Monday-Friday at 3 p.m. on ABC.
