 ::Her hair does go quite low down (second character in second pane). Not sure what you mean about personality (this character doesn't say anything). Personally I still think its Danish.

-Is it not possible and even likely, due to the simplistic nature of the dialog here, that the falling stars here in fact have nothing to do with black holes and merely refer to "falling stars"?

 ::I must say that my first too hasty view of the comic page had me reading "...haven't seen a star fall''ing'' since...", and thus about "falling stars", i.e. meteorites (which... well, is another astronomically naïve 'fact'), but on a second reading I correctly realised it as "fall in" and therefore could only really be relating to the black hole thing that closes the comic-text.

-::TDEs do happen, I don't question this aspect. I think most normal stars will be strongly deformed if not torn apart but more compact, "stiffer" object can easily cross the event horizon / Schwarzschild radius of a SMBH without structural damage. I couldn't find any publication right now but I guess neutron stars woud cross the event horizon quite unaffected because they are so small and the gravitational gradient across them would be orders of magnitude smaller that its own gravitation. But the text was changed to "usually" already - can live with that :-)
