I've now rewatched "Heritage" and "Kingdom" on DVD. No new thoughts on "Heritage", but I still really enjoy the gargoyles bringing Cagney to the clock tower to look after him in Elisa's absence. I thought it appropriate that it was Broadway who found the kitty (he's the one of the four left behind gargs who's closest to Elisa). And I liked Hudson's rapport with Cagney, while missing Bronx. Including Cagney rubbing affectionately against Hudson - he's got no problems with gargoyles (though Maggie's another story).
I found myself wondering how that containment unit was still functioning after Fang ripped the cables apart to transport it. (To make up for it, I noticed this time around - and really liked - the way they did Talon's voice while he was stuck in there.)
As you pointed out in your ramble, Xanatos's security system does far more damage to the castle than to the gargoyles - I cringe as I see it blowing pieces of the castle apart (small wonder that, by the time of the Double Date story, Owen was getting fed up with all those repairs!) - but Xanatos's lines made up for it.
Xanatos is just so much fun...
