Batman and Robin Adventures #1 (2016)

Steady weekly sessions with his ex-fiancée Grace - as well as Bruce Wayne - give Two-Face new hopes for recovery, and reforming his life as Harvey Dent. Unfortunately, these visits attract attention from the Joker, who spitefully suggests that Bruce is actually courting Grace for himself and only feigning goodwill while actually paying Arkham to keep Two-Face incarcerated. Though rejecting these suggestions at first, Two-Face grows suspicious when he learns - from a newspaper planted by the Joker - that Bruce has personally invited Grace to a garden party celebrating the Wayne Foundation's latest redevelopment project. Emboldened, the Joker next steals a radio from Arkham's orderlies, and orders a still-fugitive Harley Quinn to infiltrate the party for more "evidence" of an affair. Disguised as a reporter, Harley soon finds the perfect indiscretion at the party: while Bruce has no designs on Grace, she admits an attraction to him, and the two share a slow dance as well as a kiss on the cheek. Harley photographs their kiss at its most suggestive angle and rushes the picture - along with "news" of their engagement - to the society editor of one of Gotham's leading newspapers. In doing so, she unwittingly exposes herself to both Bruce and Dick Grayson; the duo give chase as Batman and Robin, but fail to capture her. The next morning, stories of the engagement reach Arkham, instantly enraging Two-Face. Believing his worst suspicions confirmed, Two-Face abandons his recovery and escapes, planning a brutal revenge on both his "betrayers" - starting with Grace.
