Aid another just gives you a plus 2 to your grapple checks for each person helping according to the pathfinder srd. Does not specify how long the bonus lasts but I'm guessing just for the nect roll. Three on one is gonna doom the guard to stew in a gut methinks. Even if she manages to get back out we can keep giving Khei the bonuses to gulp her back down. Also, I believe you also get plus 5 to rolls to maintain grapple once you have someone held and they don't break free so that guard is not likely to escape her fate as Kuru pudge.<img alt=":gulp:" src="./images/smilies/munch.gif" title="Eat!"/>
