The implication of Aurelia last strip discussing making her paramour lose turgor and then Marigold discuss something going up her nose is that this was Dale's... emissions. Mind you, bedroom activity calamities aren't really one or the other participant's fault, but you tend to still say sorry when you do the thing that causes your partner discomfort (and for all we know, Dale did, but Aurelia doesn't either, something that would get straightened out with Marigold's next statement were there not this interruption with the actual plot of the day).
Re: May -- May was in the wrong there. May is coded as being crass and insensitive. We've seen her slowly mellow in that behavior, but I don't think she's supposed to be becoming a toothless crass individual (Pintsize seems to be capturing that role, for the time being).
