To business then!
For simplicity sake, I am going to call the targets #1, #2, and #3.
Here are their locations, according to Ohanzee's AROs:
#1: ground, about 8m from Ace
#2: ground, about 10m from Sam
#3: tree, about 20m from Ohanzee
And here's what each of you can see with the help of Ohanzee's AROs:
Ace: Jack squat
Sam: #1
Ohanzee: all three via assensing
I'll take the liberty of rolling initiative:
Ace:
Initiative 2d6+8:

Initiative 2d6+9:

Agility + Unarmed + Charging:
12d6t5 2 hits@rednblack, Technically this is a surprise attack since Ace can't see his attacker, but I'm going to say that Katsina's spell gives him the opportunity to make a surprise check.
1) Roll Reaction 4 + Intuition 4 + Combat Sense 4 = 12 against a threshold of 3. If you get 3 hits, you can roll defense as normal.
2) Defend against 2 hits.
3) Soak if necessary.
Then action is to rednblack and Poindexter. Ranged attacks are -2 if you can see the target, or Blind Fire if you cannot. No penalty for melee attacks.
