1st theory "**MULTIPLAYER HICON IS A LASSO"
2nd theory "MONA (H)IS (G)CONE (AH)HA LAST-MP3"
the 3rd idea that i made just now that it could be talking about how eida used mona as a lasso and that lasso finally broke and eida had to deal with "HI CONE" given off what the messages have said.
and that mona is now free because the lasso broke and the lasso(the lead we have now) said Became the LAST known mp3 heard from mona.
