Woah .... um . Lea as the godmother is the to ensure that Harry isn't a dud. Harry has to grow up able to defend himself from anything and Lea will make sure that he is able to hang with anyone.
Did she? Giving young Harry a Dumbo feather so he'd have confidence to go against Justin isn't exactly making sure he could hang with anyone. Actually we don't have that scene on page when Harry actually finds out he has a fairy godmother. Lea took no hand in his training like she did in Molly's case. Did she just pop up after Harry managed to kill HWWB? From the flashback in Ghost Story this happens after he escapes from Justin and HWWB turns up when he is at a gas station.. Seems to me that the Winter Court stayed pretty much hands off until they were sure young Harry had some skills.. Which goes back to the theory that it was Lea or Mab who had Malcolm murdered, because they wanted to limit his influence on Harry.. Further made sure that Eb wouldn't be able to track him down once he went into the foster system at the age of six.. This last makes no sense to me, and Eb has yet to answer those questions.. We also have no idea what Justin had in mind when he adopted Harry and Elaine.
So as we have learned over and over again, bargaining with the Fae can be tricky.. If Mab though Lea
promised to watch over Harry, Lea did... Lea checked in when he was in the orphanage as this nice lady who was interested.. That isn't preparing Harry for anything, Lea didn't do anything when Justin adopted him, guess trusting that Justin would give him a good basic wizard education, but no clue of or what Justin's agenda was... The long and the short? From Mab's point of view, and thus Lea as well, Harry was watched over, so they kept up their end of the bargain, nothing was said about training, saving, guiding... If Harry turned out to be a dud, they still kept up their end of the bargain, they watched over him.. Since Harry wasn't, Lea steps in with a Dumbo feather after he defeats HWWB.. The Dumbo feather helped Harry with his confidence, but more importantly Lea made young inexperienced Harry commit to a bargain for that feather. That bargain would chain him to the Winter Court until such a time when Mab would be ready take the bargain over from Lea and begin to pressure Harry into being her Winter Knight... Long term plan?? You bet, Harry had been roped into eventually becoming Mab's Knight since before he was born.. That's why I think he really gets pissed when he finds out the real details of the bargain his mother made with Lea and thus Mab.
