She went into more detail onInstagram, explaining that she will play Reagan, a “realistic person” who is “still figuring herself out.”

The episode will wrestle with the restrictions placed on Reagan as a “credible victim,” but Winter added that “making mistakes, or experimenting with things some may frown upon, does not mean you should be an open target for sexual assault. NOTHING anyone does could EVER possibly warrant that.”
