I wish I had more for Dot with my one-char roster but will hit you up as that expands <3
In the meantime Ida has a lot of silly excuses to be running around Hogsmeade on the basis of her family's business. They have a booming spice/ingredients trade from the East thing going on and maybe Dot's put in some special requests for her consultancy services?
If this happens then in the last 3 years they very well may have run into each other. Ida does menial tasks like quick special deliveries + posting up flyers or ads and up until this year was really aggressively trying to prove her dad that she can run part of the business. Maybe Dot got a funny sales pitch as a result xD Could be funny if that made Dot want to barter services with Ida but Ida is, uh, the Dana Scully to your Fox Mulder when it comes to superstitions.
