there's actually quite a bit of foreshadowing from the first episode alone, from the very beginning in fact. Madoka's dream is possibly an early time loop, where she still tries to reach out to madoka, but isn't heard. It transitions to the first time the viewer sees kyubey, then cuts to some further foreshadowing at the beginning of every single episode: the OP. It is brighter, more cheerful then the actual series seems to be, showing madoka' s antics and blunders as a magical girl, fighting monsters that never appear in the series. This could be what madoka thinks being a magical girl is, rather than showing anything in the series. Another foreshadowing is madoka and her mother in the bathroom, the bathroom is huge, has lots of empty space and the only two people here are madoka and her mother. The series has an odd habit of ruining it's own sense of spacial awareness, particularly when there is only two or three characters on screen, almost like it's a stylistic choice to isolate the characters. Not really foreshadowing, but may be a bit of a clue as to the shows nature to show, not tell, madoka 's mother seems to be dressing for work, but doesn't mention her job. Her makeup is labelled with numbers and she tells madoka how beautiful young women should be, which makes me think she's like an Avon rep, where she has to use the product she sells. More foreshadowing as homura is introduced as a transfer student, seems to be typecast as a kuudere and shows interest only in madoka. Kyubey appears again, but doesn't make direct contact, I'm thinking the sudden appearance of homura interests him (he doesn't have time travel powers, where as this is another cycle for homura) and seems to be interested in some of the young girls at school. Around about the time madoka and sakara start shopping, kyubey plans to make contact but homura finds him before he does, kyubey shows his interest in madoka by contacting her telepathically, where as sakara doesn't hear anything. Bebe is introduced just when the girls are pulled into a witch's labyrinth, and summons a countless number of guns, suggesting the power of witches and magical girls are a miracle and makes them nearly godlike.the last part of the foreshadowing is kyubeys last line in the episode, promising if madoka and sayaka form a contract with him he'll make them magical girls. The question is, why would such a miracle need something as clinical as a contract?
