I was thinking about Heather's Role in the Resistence if she happened to be a character in Sonic Forces, though everyone else would dream of fighting side by side with Sonic and the others, Heather is not made for fighting, in fact she is the quite opposite of a fighter!
So she tries her best helping in a different way, in the REsistence she would act like the Maid for everything, a Nurse, a Cook etc. taking care of the other Members of the Resistence, keeping them well fed and happy, well at least as much as possible during a war^^
And she seemed to be pretty popular! Her motherly behaviour connects with many people^^
Hope you like that idea, something silly I made up in my mind^^
