Thanks. I figured it was sometime after Skin Game, but I wanted to check and make sure, in case it was a prequel kinda like how "A Fistful of Warlocks" was for Luccio.

There are several other short stories after Skin Game as well, i.e. Jury Duty, Zoo Day, etc.  Does it matter where Monsters fall in relation to them?

Wait- what is Zoo Day and were do I find it?

Ok, your saying that he gains the skill threw me off, because he has already used it effectively, but other than the demonstration of the skill that Lash did, Harry hasn't had any apparent benefit from any knowledge of his power greater than what he already had without the knowledge.  However if he reacted to that knowledge by taking his head out of the sand WRT his mom and started investigating his own whereabouts, I would say that this knowledge did some good.

Yes it is a semantic thing, but perhaps one with some importance, and on further thought I would like to replace 'ability' with 'talent' as defined below.

Talent =a special natural ability or aptitude: ie. a talent for drawing.  something that you are born with not learned
Skill= the ability, coming from one's knowledge, practice, aptitude, etc., to do something well:ie. Carpentry was one of his many skills.

From this viewpoint, Harry's magic is a talent, while his use of veils would be a skill developed from that talent.

We probably need to know more about the nature of his connection to Outsiders and what it will allow him to do to fully classify it.
Is it just a part of his nature (like an immunity to poison ivy) that requires no active, conscious participation by Harry?
Is it a talent that can yield more with study but can be accessed on an instinctive level for somethings like self defense?

I do agree that at this point he hasn't really done anything with the knowledge (or perhaps awareness is a better word) that he has this quirk of birth, IIRC he hasn't even asked Bob about it (at least not 'on screen').

Of course these thoughts may be thread drift and not relevant to the list of power-ups. Also, I haven't been on the forum long so there could already be well held theories that I'm missing that have already defined this connection to Outsiders.
