My god. You are lame as hell. There are 0 people who would guess "oh yeah, jons the lovechild of rhegar and lyanna" after watching those 2 episodes fresh. At minimum, you would need context of the story pr multiple rewatches if not book knowledge.
Saying you expected jons story to be something odd, sure. Thats reasonable. But with just two episodes of knowledge, there is no way you would jump to "oh yeah, robert and lyanna werent anything and jon isn't neds bastard". You might think ned is hiding something but if anything you would think he is hiding an affair with a targ woman or something. Neds sister died in a war in which she was supposedly captured and raped. Without knowing any other background and just watching 2 episodes, no reasonable person would think "fuck, musta died dyring childbirth of the crown prince". Thats insane and laughable. If those are the jumps you make upon first viewing of every show with no previous knowledge, you must be seriously disgusted with the mundane realities of television.
