As we previously reported, Gossip Girl is about to welcome back Billy Baldwin as Serena's dad.

The circumstances surrounding his return to New York City? They're not good. They never are.

According to the official episode synopsis from the CW, a “family crisis” brings him back. It's unclear what that consists of, but we have a feeling it may be related to the unnamed, upcoming death on Gossip Girl.

Meanwhile, Blair thinks that Cyrus may have found a potential loophole in her prenup with Louis, Chuck and Georgina partner up in a scheme, and Chivy looks like she has some serious explaining to do.
