Fighter: Barbarian's fratbro drinking buddy

Wizard: Fighter's emotionally distant and verbally abusive father-figure

Monk: Wizard's even more emotionally distant and verbally abusive father-figure

Sorcerer: Monk's third ex-spouse, mostly along to look after the Fighter because he's like a little brother to her

Ranger: Sorcerer's daughter by a second marriage and also the Druid's husband (which has led to some confusing moments with the cleric)

Bard: Rogue's legal defense counsel

Gotta go quest to the third circle of hell to make amends in recovery
