Meet Luke Gulbranson's Sister Alli, Who Taught Him "A Lot in Understanding Women"

Things came to a head for Hannah Berner and Luke Gulbranson as they experienced one of their most heated arguments ever about the nature of their relationship prior to Season 5 of Summer House in the February 18 episode of the show. Now we have your first look at the morning after.

The above Bravo Insider exclusive shows how the Summer House roommates are recovering from all of the intensity between Hannah and Luke the night before, which we will see in an all-new episode on Thursday, February 25 at 9/8c.

While Hannah recaps the events of the night with Ciara Miller, Luke catches up with his older sister, Alli, via a FaceTime call. "My sister Alli, she's four years older than me and taught me a lot in understanding women," Luke says in the clip.

The Summer House cast member goes on to explain why his sister is the perfect person to go to for help with his problems. "Me and my sister confide in each other a lot. There was just things that we saw and went through as kids that made us really close with each other," Luke shares before opening up more about some of the hardships he and his sister faced with their parents while growing up. "To have Alli in my corner, I feel very lucky."

Luke opens up to Alli open what's been going on with Hannah, and his sister doesn't exactly see things the way her brother sees them. To see the siblings' FaceTime call, as well as a potential business crisis for Loverboy, sign up to be a Bravo Insider.
