keep an eye on that list, the last seen column should tell you if this is current of ancient activity, if he/she is seeding, correlating this with times your roommate is home (or his/hers pc on) should give you a good idea of whether this is him/her or someone else sharing your IP. Another such file coming up on that list is a strong indicator as well, and could help you even if he/she is no longer seeding. Keep in mind that remote control of a torrent client is possible. If you control the router you could try getting a new IP. All this without downloading the actual file

Thanks for the advice I'll keep an eye on it. As far as I'm aware he's home basically 100% of the time so that unfortunately doesn't help narrow anything down lol
