She was nervous about her younger sister moving in to the Forrester Mansion to begin with, and now, Maya (Karla Mosley) will begin to see her hesitations were warranted on The Bold and the Beautiful.

Ivy Confronts Rick and Maya

She didn't want her sister to move in, but Rick (Jacob Young) insisted on letting Nicole (Reign Edwards) live at the mansion so she would no longer be crashing on a friend's couch. And after a talk with her sister, Maya began to think it would be okay to have her sister stick around-and has let her guard down as a result.

Now, she feels confident things will all be okay-and is making sure Rick knows how grateful she is for everything he has given her.

Nicole Becomes A Threat To Rick And Maya's Happiness

"Thank you for being the best thing that's ever happened to me," she says to him in a preview clip for the Thursday, March 12 episode.

However, when she gets back to the mansion and sees Nicole is still there, she may begin to start questioning her sister for her reasons to be there once more-and when she does, Nicole will issue her a warning that she won't be going anywhere easily-especially if what she suspects to be a big secret Maya is keeping turns out to be true.

"I'm not going to be swept under the rug just because you're ashamed of me," she tells Maya in the clip.

The Bold and the Beautiful airs Monday-Friday at 1:30 p.m. on CBS.
