err cool you you found it but you realise you posting it up can ruin the challenge for others who haven't done that yet

Hey, I gave a fair warning and bumped it down with dots (besides, the actual spoiler isn't until the VERY bottom).
If someone decides to read further it's their choice, I think it's plenty fair enough.
If it spoils it for someone, it's their own fault.
