If you’re missing the Kathryn Hahn of Parks and Recreation’s season 4 – literally, who could forget her trist with you know who — she is back and ready for action in Parks and Recreation season 5. And she’s not the only guest star making an appearance: Lucy Lawless and comedian Jon Glaser join the cast.

In season 4, Hahn played the cold-hearted, yet incredibly talented Jennifer Barkley, who came to Pawnee as Bobby Newport’s campaign manager. It was Hahn who invited Ben to come to D.C. to work on a congressional campaign with her at the end of season 4, and though she was missing from the (magical) first episode of season 5 that premiered last Thursday, the Seattle Post Intelligencer reports she will return this season to reprise the role of Barkley. Parks airs at 9:30 p.m. Thursdays.

And if Hahn isn’t enough to lure you in, then get ready for Xena, Warrior Princess. Lawless, who played Xena, joins the cast of Parks and Recreation as Ron Swanson’s new love interest. (And you’ll be shocked to find out, her name isn’t Tammy.)

Spoiler Alert: Lawless leaked to Entertainment Weekly that her character has two young daughters who may or may not wreak havoc on their relationship. And if the photos we’ve seen are true… the daughters’ nefarious activities may lead to Ron in face paint. (Does paint come out of mustaches? If the mustache is injured we have to believe it’s over.)

Weekly reported that Lawless said, “This is his first mature relationship — she doesn’t pervert his nature in any way… This is the sort of woman that you might want to see him with, and yet it’s going to be damn near impossible for him to stay in it.” So she’s not going to fight for him by drinking Leslie into a stupor a la season 4? She’s not going to make him shave his mustache (Tammy One) or cornrow his hair (Tammy Two) or move back to the farm (Tammy, his mother)?! Who is this woman and how will she break our beloved Ron?

This season also promises guest star comedian Jon Glaser, who will play Leslie’s nemesis in the City Council: Councilman Jamm.

What guest star are you most excited about and why? If you could face paint Ron Swanson’s face… how would you decorate it?
