Asriel found Chara in the RUINS, though. For him to be able to find Chara in the Ruins, he had to have lived there.

That and the glpyhs is exactly why I considered the monsters moving out as a two-step process:They started to move out in Early 201X, which is why the calendar of HOME stops there, and the arrival finished at the END of 201X, when Chara actually arrived there.

..Wait.

The line that I thought proved this disproves it.

It was referred to as "The Ruins", rather than its original name "Home".

It was already the Ruins. The monsters already moved out.

..But then, how did Asriel end up in the Ruins? What brought him to Chara?

The monsters' original place at HOME had a bedroom and a chair for one child:This was more than likely for Asriel, especially considering the file name of it. (It's room_asrielroom)

This places the movement to New Home between Asriel's birth and Chara's fall. Given that Tape 1 wound up in the True Lab, they likely moved not long after Asriel's birth.

..Good job. I'll have to adjust my timeline.
