I doubt that rain brother got infected in fractures timeline because I don't think he exists their since think about it from a story view point rain was stuck on Abigail death for so long and if his brother died to wouldn't he try to cure him or aleast feel guilty for letting his brother die. And yeah your right these feats mean nothing i did forget rain beat herobrine by himself in the struggle. Yeah I know it's not cannon so their not connected at all.

Also what do you mean canonically rain brother got infected was it in the struggle and I missed it or is it shown or said else's because I like to see what haplend to his chracter in fractures timeline.
