text: Other than Veronica, Reggie is romantically interested in Midge Klump, the girlfriend of brawny but dimwitted athlete Moose Mason. A running gag in the series features Reggie attempting to spend time with Midge without attracting Moose's anger and jealousy. He occasionally seeks to date other women, including Betty Cooper. Reggie and Betty frequently join forces to try and break up Archie and Veronica. In some stories, Reggie and Betty are shown to be a couple, even though their respective interests still lie with Veronica and Archie; for example, the Life with Archie series portrays a future in which Archie marries Veronica and Betty and Reggie are a loving couple. In other storylines, Reggie has occasionally been known to date Cheryl Blossom. The two have very similar personalities and, at one point, before she dates a boy named George, try going out together. Like Betty and Veronica, however, Cheryl mainly uses Reggie as an alternative to Archie. Another arc features Reggie falling in love with Veronica's cousin Harper and developing a long-distance relationship with her.
  Reggie is insanely jealous of anyone else but him being in the spotlight, and will sometimes deliberately cause them trouble to get what he wants.
  On certain occasions, Reggie shows a kinder side where he will come to the aid of his friends or total strangers, although he prefers to keep these good deeds secret. In one comic, he has a close childhood friendship with an elderly woman named Mrs. Finklehoff. Due to Reggie's reputation for arrogance and scheming, his peers often distrust his motives even when he is genuinely intending to help someone.

Hot Dog's subsequent reanimation results in him infecting Jughead and starting the zombie apocalypse.
