"I honestly can't even remember the last one that I went to," McCullough tells Soap Opera Digest
. "The Nurses' Ball [became a big deal] because of Stone," Robin's first love, who lost his life to AIDS in 1995, "so it's nice that I actually get to show up."
The popular actress is happy to be back. "In December, when we shot the happy ending of Robin going off into the sunset with Patrick and Emma, he was like, 'Oh, we're definitely going to have you back.' and I was like, 'Really? How?' He said, 'Oh, we'll figure out a way.' A few weeks ago, I texted Frank just to check in, and I shared the news with him that I am directing another episode of PRETTY LITTLE LIARS.' He was congratulatory, and then said, 'So, are you available?' I said, 'Yeah, I'm available until the end of May, when I shoot PLL,' and then the next day, I got an email with the dates [he wanted me to shoot GH]. I was like, 'Oh, cool!' I didn't know he was serious! I'm really excited and I know it's going to be really fun."
