no, sirius was in griffyndor, but i dont know why hagrid thought sirius was bad since HE was the one who said that all bad wizards (and witches) were in slytherin, BUT in the PoA he (and everybody else, DUH) thinks that he's bad when he was in gryffyndor (and he deserved to go there because he is (more like was) very very brave) 🙂
PHEW! sorry if that confused you 😂
Both james and lily were in gryffindor...in the first film wen hermione shows harry the plaque where his dad's name is under seeker (wrong) it shows that he was playing for gryffindor...james and lily became head boy and girl in their seventh year, which is also when they started dating... they married straight outa hogwarts and joined the order of the pheonix
