I've just finished the next recruit to the Grey Knight army, this time it's a weird cherub thing. I'm not sure what he actually does (or is) but I really like the figure, he makes a nice change from all the Grey Knights so I'd like to think he'll make it onto the tabletop. Here he is:
A quick edit... It turns out that he is a familiar and, under the last codex he'd have given +1 initiative to the Inquisitor. Sadly, there doesn't seem to be the option for this in the current codex so he's more likely to be a stand-in servo skull or maybe a mystic or a psyker. I seem to remember that there are at least two other creepy cherubs out there (one with a book and one with a bolter) and I'd quite like to collect them all so that they can flutter around Inquisitor Coteaz looking suitably weird!
Here are pics of the two I've found online:
