Okay, that mess out of the way, here're the results.
1 Success, 1 Advantage, 1 Despair, FAB 2.
While this is technically a successful combat check targeting Ventress, it would certainly be against RAI to trigger Scrap 'Em!, so I won't.
With the Despair, Mireska takes a hit for 7+PB3+1=11 Stun Damage. After Reflect and Soak, that is reduced to 0. Mireska suffers 3 Strain for Reflect since this is the first time this round she's used it.
With 1 Advantage, he passes on a Boost to next. With FAB 2, he passes a Boost to Varactyl Squad.
Again, I apologize for my mistakes, I'm scatterbrained today. I'll post IC, then @MrTInce is up with Ker'see.
