-chuckle- I rather suspect Erin was a bit surprised to find out that Potter was made of less timid material and was a dangerous opponent in his own right; I don't know if this'll lead to anything being stirred up or not, but I suspect it's not going to lead to anything good.
The training and the aftermath were well-written and quite believeable and the private discussion between Orestes and Harry helped both of them, I'd think.
Meanwhile, that omaki was downright hilarious and I can't blame Harry at all for not resisting; I'm not sure I would, either. :D
