There's drama ahead in The Real Housewives of New York City's trip to Montana.

Halfway into the trip, tension between Sonja and LuAnn still lingers. While there are distractions from the drama with a full day of outdoor activities, things get tense at several points. Old friends Kristen and Heather square off in "the most unexpected tiff" of the season, per Bravo.

Meanwhile, in this clip from Tuesday night's episode, which is exclusive to The Hollywood Reporter, LuAnn and Sonja go at it during a dinner in an argument about a facialist. Watch the clip below.

Real Housewives of New York City airs at 9 p.m. ET/PT Tuesday on Bravo.
