On Monday's all-new episode of Gossip Girl, Serena is determined not to fall back into old habits.

We've all heard that before, but will this time be any different for the Upper East Side It Girl?

Looking to make a new name for herself, S throws her first adult event in "High Infidelity," a benefit for the Central Park Conservancy. Executive producer Sara Goodman previews this and more in the video below.

By Serena's side is Steven, who appears to have a connection to Sage, who Nate is dating.

"Dating" is one word for it, anyway. Nate is also in need of a new journalistic bombshell, having punted his Gossip Girl expose, and is looking to revamp the Spectator by running Dan's serialized novel.

Will Georgina and Dan go for that? We see them deciding the best way to publish his epic new work and have the biggest impact. Perhaps teaming up with Nate offers a mutually beneficial partnership.

Meanwhile, Chuck convinces Amira to stick around and find out why Bart faked his own death, and Blair will be in classic Blair form as the head of Waldorf Designs, looking to outshine the competition.

"High Infidelity" airs Monday night, the second of the final season's 10 installments. We learned the title and a key guest star of the Gossip Girl series finale, slated to air December 10, yesterday.
