A admit it is weird that when Asgore shows Frisk the Barrier, there's brilliant light all around. Yet later on it does seem to be hard.

Of course, Asgore didn't actually show us a brick wall, he showed us a corridor that stretched off into the distance still.

Perhaps there is something to find here.

But it's only when Frisk walks to the end of the final Flowey Room with it's grassy hill lit from above that the game informs us that we're leaving the Underground, and that our friends will follow us.

There does seem to be the potential loophole that "only a creature with a powerful SOUL can leave". And Asriel and Chara achieved this by combining theirs.

So if Frisk had an unusually powerful Soul, perhaps he could leave?

Could Sans have voluntarily left the Underground? Did he stay because his friends where there, and he liked it better?

More questions than answers.
