Chicago native Chris McKenna is shaking things up in Port Charles. The former sitcom star has joined ABC's General Hospital as Jack Brennan, a secretive character with ties to the WSB and plenty of drama ahead.

In a live interview Thursday on ABC 7 Eyewitness News, McKenna teased upcoming twists, including tension between Brennan and Carly and secrets Josslyn is hiding from her mother. "There's a lot going on beneath the surface," he said.

McKenna also hinted at possible scenes with soap legend Erika Slezak, who begins airing Friday. Fans spotted the two together on Instagram, along with Jessica Tuck - a former One Life to Live star who recently directed an episode.

Catch General Hospital weekdays at 2 p.m. on ABC 7.
