After their run-in with Gaggy, Harley asks the others if she sounds that lost and needy when she talks about the Joker. She prefaces this by asking them to be honest. They don't disappoint.
Selina: Absolutely. Ivy: Totally. Jenna the Carpenter: I just met you and I'd have to say yes.
On that note, Jenna the Carpenter (look up Ineffectual Sympathetic Villain; that's her there). She's a villainous carpenter, who, when she isn't planning bank heists or other nefarious deeds, makes her money doing legitimate carpentry work for various bad guys (at what are implied to be exorbitant prices). Not to mention the Broker, a real estate agent who specializes in themed villainous hideouts.
