UPDATE! MFI has now told his version of events. Go to his blog to read all about it:
Runeshark currently have this livestream going for RS2007. MFI has been watching them since they started, so he was watching this too. He was also in a Skype call with us.
As he knew where James was slaying, MFI went over there, so he could do the equivalent of 'hi Mum' calls in the background. We all watched and giggled. But then there was suddenly drama. The lad from Runeshark died, losing expensive armour and the such. The whole livestream was gasping in shock and horror.
But in our Skype call, we knew something more. We knew that MFI had picked up the whip, fury and Dharok helm. We watched in anticipation as, on the Livestream, James hurtled back to the spot. Then he reached MFI.
There was a trade screen. Hundreds of thousands of people watched MFI trade James his stuff back. The livestream chat erupted! It was so lovely! You've got the like of me, Tabt, Helm Lardar, Replacer and Jyreeil cheering aloud in Skype, as people began yelling things like 'MFI is a legend!'
We all knew already. But now the whole of Runescape does too.
I'm so proud. <3
Edit: MFI is in the Runeshark livestream RIGHT NOW! Watch from 1.06 to see the whole sequence from James dying.
Edit 2: Here is MFI's skill log!
Edit 3: MFI has appeared on the Runescape Players Wiki for this!
