That last word sound like anything but pojadz to me and I listened ten times if once.
Agree. I listened many times and she said "poy - jest".
That's basic phonetical rule [pojast] z turns into s at the end
Very interesting, Russian "поезд/poezd" is "a train", and i realised that I've never thought before about really meaning of that word, "something that едет/ rides". Wonderful:)
