Hmm.. well, did wewe try the Polyjuice potion yet? If wewe did, then wewe might be able to get into the common room kwa going through the chapter, like wewe always do.. (I haven't been on Pottermore in forever so sorry if I get stuff wrong) If wewe can't do that, then maybe , try and add somebody that's a Slytherin and see if wewe can get in then. =/
