hey there. i know the password already so i can help a bit. just as Grizz and Cerberus said: pay close to what Orlando is saying. what did he say that connects him and Tyson. it could be almost anything sure, but there is something there that might be sooo obvious that you would be like "oh my gosh i wish i seen that sooner. I can give you a password that is like a hint but Thanatos wont give it away, hopefully Grizz doesn't think of this as cheating as long as i don't give away the actual password. until i'm given approval that i'm allowed to say the actual password (not the one that gives it away) think of the sentence "He was just as irritable when I went to go talk to him." there is a password that wont give away anything but you wont access anything either except Thanatos saying you're close. make sure to read.
I really hope this helps
