Also, when was 1st Timeline Fatal_Error created, didn't 1st Timeline Geno become Redacted!Error, Hobo!Error or Recall!Error?
The roadmap of 3 timelines showed that Fatal_Error appeared by the second timeline where he can either become Amalgamate(Oobleck) or Fatal_Error.
Also, thinking about it, where did 2nd Timeline Error even appeared from?
And finally, it is amusing how there were needed 3 timelines for Geno to get his canon ending without becoming Error or just to have a happy family before that went bad as well.
i like how you still remember that chart
1. but no, 1stloop!Fatal didnt come from the 1st timeline of aftertale in the chart, he's from the 2nd one
Recall, Hobo and Redacted came to be simultaneously. meaning after their split when they were one geno, they continued their different paths and errorfied at the same time.
and no new Geno proceeded them 'cause, yknow, the classic sans turned to anti, lol.
now it was 2nd!Loop!Fatal(as Geno) that was fated to either become Fatal or Oobleck
2. And by 2nd timeline Error, i assume you meant HQ!Error('cause we already know where MOE!Error came from if ya'll had read the comic)
HQ!Error is this Error, if anyone wonders
he's also the one seen in the prologue of Margin of Error
Well, he was this Sans(he's witnessing his bro getting un-alived by 1stloop!Fatal here)
After Fatal corrupted their world in the attempt to erase it as he always planned to do, Sans kinda got errorfied and survived, and became the error we see in the headquarters.
3. and lastly. lol yeah. i think the only timeline that has a decent happy(even tho the Geno here hasnt seen the surface yet) ending is one in the 3rd Aftertale timeline.
