WARNING: This article contains spoilers from Thursday’s episode ofStation 19.

Thursday’s episode started with a sweet flashback of 20-year-old Andy and Ryan, cuddled up on the roof of a car. Soon after, fans saw Andy giving Ryan CPR while repeatedly saying, “Stay with me.”

Unfortunately, he didn’t make it. Minutes later, fans joined theStation 19family at Ryan’s funeral.

“It was a surprise,” Frezza, 30, tells PEOPLE of discovering his character would be killed off. “Obviously, I didn’t know that’s the direction that Krista [Vernoff] was going to go in. But once she told me, and she told me her idea of what she wanted the show to be moving forward and how she wanted Ryan to end up leaving the show, it was a very interesting idea. And as sad as I was leaving the show, I was also a very nice way for a character to go out.”

The on-again, off-again couple has had their share of ups and downs throughout the past three seasons, but Frezza says he hopes Andy can find a way to move on.

“I’m hoping Andy will find peace,” he says. “I don’t think she’ll ever be able to find peace, because she’ll probably deal with survivor’s guilt and watching the person that she knows the best in her life die in front of her. But I think that the best thing that she can do is to try to really build a solid relationship going forward with her father, and I think that the closer they get to each other, the better they’ll be able to deal with the loss of Ryan.”
