Randal pulled his shield and 5 foot stepped back with his move action, as I stated earlier (see no reason to change his action).  And yes, he is readying himself to move through a window swinging his weapon, rather than making himself a target by flying up before he's ready to attack.  (plus, the moment when his large, feathered wings come out from under his cloak is one I was saving for a dramatic moment... and flying up and hanging outside a window at the end of a round isn't quite... dramatic enough.)<br/><br/>Having those wings come out, flying up through a window and striking down a halfling in one action... that's a bit better... so he'll wait till the end of the next round.  (although it would have been cool if he had managed to save his ability to fly as a surprise for the dragon... )
