This question will resolve Yes when Dr. Ally Louks, the ethics of smell PhD. famous from Twitter, and @Aella have some sort of substantive conversation directly related to the topic of scent before the end of the year. Otherwise, at the end of the year, this market will resolve No.

A substantive conversation should involve a back and forth discussion, whether through text or speech in any medium, that is documented in some way. A rumor that they spoke at a convention would not count, nor would one of them saying they were DMing but refusing to post it. A twitter thread where they each made multiple posts directly regarding one another, or each made one longtweet with multiple paragraphs, would suffice for Yes. A shared twitter space or podcast/panel would count as long as they both spoke on the subject while in each other's digital or physical presence. Topics such as showering or homelessness would be considered related to scent by default even if the conversation doesn't use the word "smell" or "scent", unless there is a great edge case argument that they were exclusively talking about something other than smell.
