Let's be real: Ambrose pretty much always saves the day, and it's no different in this season. He and his partner in crime (and passion!) Prudence finally hunt down Blackwood and bring him back so that his aunties can hold Blackwood hostage before he performs any more nefarious magical activities.
Ambrose not only helps Sabrina with the Unholy Regalia but he tries to save Nick's soul and is the only one to survive the apocalypse. He helps Sabrina go back in time using a temporal egg he kept so that all is right in both realms, but is worried that she's managed to disrupt time by creating a paradox. Sadly, Ambrose and Prudence break up by the end of the season, but we're hopeful they'll finally get it together by the finale.
