Quick combat rules question ...
1. Ashley is in melee with Bill
2. Bill wants to ranged attack Cody
Does Ashley get a free attack on Bill?
No. It doesn't fit the idiom of demigods fighting to worry about things like that. You could decide otherwise, however, if Ashley has done something to specifically set such an attack up, or if the two fighting are just ordinary humans instead of divine exemplars.
If Bill were to move away from Ashley without spending an action to disengage from combat, Ashley would then be entitled to a free melee attack, however.
