Neither The Light Or The Film Want Things,

tha stranger wuld b anger since itse meant to b related to williams mother since he seemingly wuld usualy see her upset or angry, tha anger reaction in conversations liek tha one wif regina & jimmy shows an obvious disliek or hatred 4 martha, on par wif williams mothers hatred fur wills crushes or othr friens, & shed seem to b especially upset by any girl friens william wuld hav nd seeing william sees martha as a frien shows why therd b motive fur tha stranger to help lila kill martha, and a possible reason why lila wuld want to kill martha since she seems 2 b somewat jealous in tha moon tarot wen Yu sees tanya, michael, an martha as williams friens.,,

tha stranger helping lila kill martha also aligns wif tha dialogue wen interacting wif items in marthas room, using tha same language william accounts his mother using wen describing how she harrassed him an his crush annie an how tha empress talks in her tarot ending..,,,it wuldn make much sense fur will to think of sum1 he sees as a frien that way

also seeing dat tha stranger wus seemingly tha one to murder tanya itse not unreasonable to assume dat he wuld continue helping ,,, also how bold text signifies wills mother in a way an how in tha rooftop dialogue wif martha U see 'william' talking in tha same bold text
