One point to make: Challenge in no way forces the target to attack the challenger. It says they are viewed as a threat and as such the target can attack, direct others to attack, etc. <snip>
So we're operating off the same page, let's use the text.
Challenge
"If successful, the target considers you a significant threat and attacks you for the next 12 Ticks. This does not mean that your target will always blindly charge forth disregarding their own safety (unless the target is particularly simple minded); how the target attacks you is their choice. For example, they may command others to attach you, use a missile weapon, or simply charge."
The wording is very clear that the target of the challenge MUST attack you. If the target of the challenge doesn't have others to order about and must find a way to attack the challenger directly, then there is a direct conflict between two mind affecting abilities.
I'm fine with Matt's suggestion to leave it to the GM at the table. I've started asking in advance for whether there are any rules that need clarification before we start for this kind of thing. I also agree that it's poor tactics to target a single target with both effects. As a GM I'd be find reminding the 2nd PC of the effect already in place and asking if they want a different target or a different action.
