Yeah, if any human would have a... free enough mind to have a similar reaction to tea to that experienced by a synthetic, it would be Emily. Not the same reaction but a similar one. She smelled Fabio Longhorn, even if she didn't see him. FWIW though, it's cute how obvious Roko is that sniffing Assam is a guilty pleasure for her!
FWIW, I've suspected for a long time that Emily is some sort of prototype synthetic, maybe a fleshbot with an AI brain. I'm not sure if this strip confirms or debunks this theory.
Off topic: Anyone know how to contact Jeph other than on on social media? There's been a pop-over car ad on the comic site for a few days now and I don't know how to tell him.
