Michele and Rob Reiner leave Conan’s party without their son after his off-putting behavior, like wearing a hoodie to a formal event and interrupting Bill Hader’s private conversation, leads to an embarrassing public row.

Reiner, however, doesn’t make his own way to Brentwood. Instead, he pops up in Santa Monica at 4 a.m. Sunday morning, checking into The Pierside hotel. Desk staff don’t notice anything off about Reiner’s appearance, but the next morning, housekeepers find sheets covering the windows, and blood all over Reiner’s bedding and shower.

The Reiners’ troubles with their middle child have been bubbling to a head for months. Every photo of the family from the September premiere of Rob’s latest film, "Spinal Tap: The End Continues," picture the 32-year-old sporting a deep scowl.

By November, Nick Reiner moves back into his parents’ guest house, which he’s trashed on multiple occasions, leading up to a blowout fight the day after Thanksgiving that left Michele “at her wits’ end.”

Ahead of Reiner’s first appearance, renowned defense attorney Alan Jackson enters the LA County courthouse, telling reporters he’s representing Nick Reiner.

Jackson says his client is still undergoing a medical evaluation at the infamous Twin Towers Correctional Facility, where Reiner is rumored to be held on suicide watch.
