You missing out the point He makes.
" cathy pic" event happened in episode 4. After that Rusty changed the password, and according to him started to put the laptop into the safe, and the other members had to ask it from him, if they wanted to use
But during the incident with Cathy , in that time the Sex tape was not on the Disk laptop, because that happened in episode 5, when the password was already changed, in theory.
So it's more than likely they are not the same person, or it can be , but then it wont be a Dik, it would be the Nerds. They Hacked it both time. I think the Nerds will be behind it, in both case. and the Jade sex tape is optional anyway , so it could be easily explained that , yeah the nerds know how to hack the dik laptop, and they still have acces to it even after Rusty takes some security messures
Tommy, could been the one behind the Jade sex tape leak. May be to gain advantage over MC , who is threatening to his Vice president status.. But Tommy is definitely not behind the Cathy leak, because he would gain nothing from it.
