New CBS president Glenn Geller raised the possibility of a crossover between his network’s “Supergirl” and the CW’s DC superhero drama “The Flash.”

“I have to be really careful what I say here,” Geller said when asked by reporters during the Television Critics Association winter press tour. “Watch and wait and see what happens.”

The answer is in stark contrast to previous answers given by former CBS president Nina Tassler, who always downplayed the possibility of a crossover.

“Right now, we’re not doing it,” Tassler said at the last TCA event, in July 2015. We’re doing it promotionally, but we’ll always stay open. They’re very inventive about what they can and will do.”

“Supergirl” and “The Flash” already share a team of executive producers, with Greg Berlanti, Sarah Schechter, Andrew Kreisberg and DC’s Geoff Johns behind both shows.
