LOCH is famous for the 4 (or 5) Greats. As interesting as GJ/HR are, LOCH wouldn't be LOCH if it weren't for the Greats.
What would happen if the following situations happened:
HYS/YD/OYF instead of H7G when H7G first met GJ + HR together and was baited by the chicken? Would they teach GJ anything, or would this be the death of GJ?
HYS/YD had to share a boat with OYF + snakes and him intent on getting 9Yin from GJ? How would they cope? And then sharing an island with OYF?
YD/H7G to replace HYS in all his dealings with LMC, would LMC be still alive?
If HYS/H7G/OYF found out their loved one was messing around with WYS's brother ZBT? Would ZBT's legs still be there?
