I don't think it's sensible or reasonable to expect anyone here to not discuss Heartstopper and its fictional characters in any way, shape or form when the legally-aged subject of this thread stars on Heartstopper and any content they provide for this thread next season will pertain to its already written and published storylines. It's gonna come up in some way.
If LPSG intends to crack down on people discussing Heartstopper vis a vis its adult actors and the content they will be performing in, I'm sure they will let us know themselves.
