20 years ago, Alina decided to flee the human continent, distraught after her mother, Jessica Grey, forgetting her promise to attend Alina's ballet recital, and her constant inability to bond with her child due to being the leader of the AMD, therefore lacking time.

Asgore told the monsters that every human who fell in the Underground must be killed, which put Alina in serious danger of death.


We don't know how the battle took place. However, coming from one of Camila Cuevas' several comics, it was shown that the girl only wanted to return home after soon realizing that she made a huge mistake entering the Underground. However, Asgore ended up killing her just like he did with the other human children.
