Q 64
Hitting your ally by chance: It comes up every now and then and I think I read something alike, but I cant find the exact rule.
Is there actually a chance to hit your ally if you
a) range attack into melee or b) melee attack into a grapple? Or was it only ranged into grapple?
Or is it just the normal attack modifiers? (-4 for ranged into melee I believe)

Q65
Can you hold a 2HW in 1 hand? - Not wielding it of course, but to use the other hand?
For example, you use a reach weapon, but the enemy is in your face, can you hold onto your weapon and just punch him in the face with your fist?
