Good Omens AU Pre-Season 1
where the archangels are well aware of The Arrangement, visit Aziraphale more often in hopes of mitigating his loneliness and thereby limiting the number of times he's turn to a demon for companionship, not knowing that they are pushing Aziraphale into Crowley's arms in the process.
During the Victorian Era, concerned for Aziraphale's well being because Crowley has been tempting humans into Lust a particular lot of late, Saraqael visits Aziraphale's bookshop not long after it opens (after Gabriel brings up replacing Aziraphale with Micheal but before Crowley asks for Holy Water) and has a long talk with Aziraphale about "Not falling for the Demon's Temptations, no matter how pretty he looks! I don't care how dashing he is in a tophat or how endearing it is when he swings his cane in circles when he's happy, Aziraphale, don't you dare fall into bed with him!"
A little while later, maybe a year or so, but still before the fight over Holy Water, Saraqael gets a Prayer-Message from Aziraphale: "I didn't even want that from him, but thanks to you, I can't stop thinking about it, and I hinted at it to him, and now Crowley is running away from me, terrified! This is all your FAULT Saraqael!!!"
