The former members of TeamArrow might not be able to spend their nights playing vigilante anymore in the new season of Arrow, but it looks like old habits die hard when it comes to Felicity (Emily Bett Rickards) and Curtis' (Echo Kellum) team-ups.

In TV Guide's exclusive sneak peek at Monday's new episode, Diggle (David Ramsey) is ready to take on the thieves of an ultra-high density renewable battery with his snazzy new ARGUS team, but they're not the only ones piecing together the mystery of this crime. Curtis (who has been left out the briefing, being a measly tech guy) obviously has to show off the specs for this cool new battery to his bestie Felicity, who immediately goes into vigilante mode. It doesn't help that the tech used to steal the battery is the exact same kind as the one Diaz (Kirk Acevedo) used to break into Felicity's secure Witness Protection safe house. Hmm...

Felicity eventually deduces (and Diggle confirms in his own briefing) that this heist was pulled off by the dreaded Longbow Hunters. These baddies were name-dropped last season, but we have yet to see them in action. Something tells us if they're partnering up with Diaz, we won't have to wait long for them to arrive in Star City. And with Oliver (Stephen Amell) still in jail, it might be up to the rest of Team Arrow to take these guys down.

Arrow airs Mondays at 8/7c on The CW.
