'Pretty Little Liars'
Rosewood is getting a lot more crowded. According to Pretty Little Liars showrunner I. Marlene King, season seven is the “summer of reunions,” which has already been seen with a trio of major returns in the first few episodes.
Below, The Hollywood Reporter rounds up who has popped up in the Freeform drama so far, and who else will appear before the season — and potentially series — finale.
Mona Vanderwaal (Janel Parrish)
Mona always shows up in the nick of time, and in season seven, she saved the day when the Liars abandoned Lucas' (Brendan Robinson) car in the woods after they struck and killed Dr. Elliott Rollins (Huw Collins) with it. Of course, Mona knew someone who could fix the windshield without asking questions, and she is now working with the girls to help track down A.D. and his or her motives.
Jenna Marshall (Tammin Sursok)
Jenna was last seen with Sydney (Chloe Bridges) at the winter masquerade balls in season five, but she made a triumphant return in season seven. Her motives are questionable, as she was linked to A.D. — or at least Archer Dunhill, Dr. Rollins’ real identity — but she has not made any direct moves to hurt the Liars yet.
Noel Kahn (Brant Daugherty)
At the tail end of episode five, Noel was seen at The Radley with Jenna and Sara Harvey (Dre Davis), but the details of their relationship have yet to be revealed. Noel previously dated Jenna — and Aria and Mona, at that — and was last seen when Spencer blackmailed him in season five.
Jason DiLaurentis (Drew Van Acker)
Alison’s (Sasha Pieterse) brother, Jason, will be back for a family reunion of sorts with his mother’s twin, Mary Drake (Andrea Parker), and Ali this season.
Paige McCullers (Lindsey Shaw)
Paige, Emily’s (Shay Mitchell) former love interest, will return to Rosewood in episode eight for a few episodes. Emily and Paige's relationship ended in season five when Lindsey moved to California. 
Wren Kingston (Julian Morris)
In June, King tweeted that Wren will be back in season seven, but did not confirm for how long or if it will be in the first or second half of the season.
Holden Strauss (Shane Coffey)
Holden, Aria's (Lucy Hale) former fake love interest, will return in season 7B. He was last seen in season three, helping Emily find out where her ex-girlfriend Maya was last seen alive.
Sydney Driscoll (Chloe Bridges)
Sydney has not been seen since season five, when she and Jenna thought that Ali murdered Mona. Later, it was revealed that Mona faked her own death. Freeform confirms that Bridges will reprise her role throughout season seven.
Pastor Ted (Ed Kerr)
Ashley Marin's (Laura Leighton) former fiancé hasn't been seen since season five, but Freeform confirms that Pastor Ted will return in season 7B. Last he was seen, some information about Ashley's unsavory past was revealed.
Pretty Little Liars airs Tuesdays at 8 p.m. ET/PT on Freeform.
