Aziraphale & Crowley
Honestly, at that point, Crowley would have gone to the gathering just for the free alcohol. If it weren't for keeping a brave face for Trixie, he probably would have been drunk since the moment they got the message from that woman. But a glass or two to take the edge of his nerves off wouldn't hurt.
He found his husband at a table, looking ready to jump out of his own skin. He set both glasses of wine down on the table before reaching for Aziraphale's shoulders, giving a gentle rub. "You're so tense, angel. Calm down. No one is snatching her here, not with so many people who adore her around." It was true, at least. No one who met Trixie didn't absolutely worship her. It would be impossible to steal her away without at least someone being alerted. Especially since their kid had a tendency to be the center of attention.
