if it helps any, Diego is extremely unlikely to think of that as a possibility, since as far as he's concerned he and Alastor just have a phenomenal connection+dynamic as dominant and submissive and that's definitely all there is to it. lmaoo
but that's probably going to have to be strangled out of them rofl. or brought up in a finder ad but also would almost certainly lead to denying it by going "more lies bullshit right? right!!!!"
But also he absolutely doesn't think Alastor would date him... though they've had dates. If he lets himself get hopeful though, he knows what will happen. >.>
