SALT LAKE CITY, UTAH: In the latest episode of 'The Real Housewives of Salt Lake City' Season 4, Whitney Rose grieved the loss of her best friend Shari Quai. Whitney sought comfort and support from her 'RHOSLC' friends during this difficult time.

However, her heartache deepened when Lisa Barlow appeared indifferent at Meredith Marks' jewelry line event.

While Heather Gay was consoling Whitney with a hug, Lisa interrupted their conversation to give Heather a piece of jewelry.

However, Whitney was quite disappointed with Lisa's reaction and noted in the confessional, "Lisa was the first person I told that Shari has passed."

She added, "For her, to act like I'm not even existing right now, its hurtful." The two then had an explosive conversation and Whitney confronted Lisa and said, "It hurts when you walk up and you go right past me and go straight to Heather."

Whitney noted that she needed Lisa to comfort and hug her. However, Lisa noted, "I can't always keep a mental calculator of everything going on for everyone at all times in all moments."

Whitney slammed Lisa back in the confessional, "I have been talking to you about it for the last five days and I texted you last night. Does she need an abacus to keep track of that it was less than 24 hours ago."

Lisa and Whitney's conversation turned into a dramatic feud and Whitney called Lisa 'selfish'. Whitney walked off the event and Lisa followed her furiously.
