Oops, who or what will come between Severide (Taylor Kinney) and Kidd (Miranda Rae Mayo) on the October 2 episode of Chicago Fire?

NBC aired a promo for Season 13 Episode 2, "Ride the Blade," after the premiere, and it offers a look at what appears to be the two in the middle of an argument. "You lied to me!" she says angrily, and it appears she's talking to Severide. The logline offers some probable cause: "After Damon [Michael Bradway] disobeys Kidd's orders during a phone call, he turns to Severide to protect him. Herrmann [David Eigenberg] searches for the perfect scent to spice things up with Cindy [Robyn Coffin]."

Kidd has already asked Severide to let her talk to his half-brother first following phone calls she saw her husband do so when they returned to 51 in the premiere. And showrunner Andrea Newman told TV Insider as part of our Fall Preview, "It's a very complicated love triangle with Kidd, whose relationship with her husband is influenced by Damon." But what exactly is Severide lying to her about?

What we do know is that Severide and Kidd are at least on the same page when it comes to the new chief, Dom Pascal (Dermot Mulroney). While Kidd was the more guarded at the beginning of the premiere, by the end they're both in agreement that there's something "off" about him. And that sentiment continues in this promo, which opens with him using the punching bag in the firehouse and Cruz (Joe Minoso) saying, "Things aren't right in the house." (He could also be referring to Severide and Kidd, considering he saw his lieutenant pause when Damon went downstairs during a call.) There's also more tension between Kidd and Pascal, after she put off sitting down with him to discuss the conversation during the premiere and he tracked her down.
