My icon isn't really that appropriate for this, but I had to use it to coordinate with yours. :P
Anyway, I should also add that Cormac is also a bit annoyed at Allegra because a) he thought he was being helpful and a good friend rather than the insensitive arse everybody saw (that's how his brain works - go figure); and b) Barney jumped to Allegra's defence, and ever since Barney and Allegra have mock-flirted in the past Cormac has felt a little jealous of Barney (though he's too dense to admit even to himself that he's jealous - again, go figure). So yeah, Cormac isn't mopish, but he'll glare at Allegra's way if they ever cross paths and she makes a point of ignoring him.
Again, like Julie, feel free to ask me about any details. These two crazy kids make our heads spin.
