"He is still a cop, but he lives in Rosewood, she lives in Washington, D.C., so there's a very complicated and long history between them," Troian Bellisario says

They’ve made it through death hoaxes, mental breakdowns and pretending to play for the ‘A’ team, but for Pretty Little Liars fan favorites Spencer Hastings and Toby Cavanaugh, things aren’t looking good five years down the line.

“No, no hope. Toby’s dead and Spencer’s moved on,” star Troian Bellisario joked to PEOPLE at Paleyfest in New York on Sunday. “No, you’re going to have to watch and find out. Things are very different, I will say that.”

Absence apparently doesn’t make the heart grow fonder for her character Spencer, a braniac who graduated from Georgetown University and works in politics, and Keegan Allen‘s Toby, who became one of Rosewood’s finest (well, this police force’s skills are definitely debatable) last season.

“He is still a cop, but he lives in Rosewood, she lives in Washington, D.C., so there’s a very complicated and long history between them,” explained Bellisario, 29, of where Spoby stands in season 6. “And that doesn’t often lead to a very good relationship.”

Bellisario revealed that Spencer studied for a semester abroad at the University of Oxford and then spent the summer traveling around Europe, “where she bumped into somebody from her past,” which will shape up to be a “very important storyline.”

And yes, she saw her hyper-competitive sister Melissa (Torrey Devito) and their shared former flame Wren (Julian Morris) while in England: “I think she lived with them for a while, which is super weird,” Bellisario added.

Melissa and Wren were both indicted in popular ‘A’ theories, but Bellisario said Spencer is getting along better than ever with the couple.

“After Melissa kind of came out with the fact that she tried to protect her by burying Bethany, I think that that really changed their sister dynamic, and I think that Spencer’s relationship with Wren probably became very familial,” she said. “I think she probably was like, ‘This person is back with my sister and he makes her happy and she makes him happy,’ so I think she just wanted to become a sister.”
