Pixel 5a also still has a headphone jack

Suppose there was a comment thread containing a back-and-forth conversation between a kbin.social user and a lemmy.world user. What would a user on beehaw.org see, given that they are federated with one but not the other?

Women on this thread: cries in no pockets

So for a Beehaw user, would they see all of the the Kbinner's comments and it would look as if they were talking to themselves? Or would they only see the top level Kbinner comment and nothing else (due to their instance not seeing the Beehaw comment and therefore not seeing children of that comment either)?
