its actually fucking insane and tragic the original ending of alicia and gilbert were
gilbert being SA by that girl And alicia being pushed to death by that said girl i know she didnt do it now in current timeline but that tragedy is insanely dark to me it makes me think maybe gilbert's best friend turned back time for them i imagine how heartbreaking it must have been when alicia died and girlbert heard the news i think he would have broken down and seeing this maybe the best friend helped somehow
