Relationship between Grog and Vex'ahlia

Vex'ahlia has kissed Grog twice: once when he was comatose in the Underdark and once after the Slayer's Take trials when he expressed disappointment that Keyleth got kissed and he didn't.

During his rematch with Kern "The Hammer", she flashed her chest at him from the sidelines and yelled "I love you, Grog!" in an attempt to encourage him, but he was too focused on the fight to notice.

Grog once tried to haggle with a merchant the way Vex does, although he actually ended up making a worse deal for himself. He didn't seem to realize his mistake, saying "Vex will be so proud of me."

During Vox Machina's fight against Kevdak and the Herd of Storms, Vex saved Grog's life by swooping down on Death from Above (her Broom of Flying) and placing Grog in Raven's Slumber. She later released him from the necklace directly above Kevdak, allowing him to land the killing blow against his uncle.
