The man -- not sure who he is -- just launched as he hijacked the party. After throwing the wine, the dude picked up a chair. You see Tom run into frame trying to calm things down, as another security guard restrains the guy by grabbing his arms. An aggressive tug-of-war then begins.
The TikToker who shot the video says the dude is not a cast member and was not going after Tom. The TikToker said, “We were just sitting at a table and this random guy came and he grabbed the centerpiece [of a] flower vase [and] chucked it at the security guard.”
