The Worg, apparently as frustrated as Rodimus, gives a low growl punctuated by a sharp bark. You suspect it must have been some sort of command in Worg, for two of his companions immediately leap forward, going for the half-orc's throat.
The worg leader seems especially warry, and prepared to defend himself. (OOC: Surprise round, Full Defense.)
Rodimus may make a DC 12 sense motive check. If succesfull, he may act in the surprise round.
All roll initiative. All but Rodimus make a DC 12 listen check, failure means you are sleeping and remain asleep for round 1, only.
