what happens when a PC melee attacks a monster grappling another PC?

[tleilaxu]

a monster successfully grapples a PC

is there a chance the attacking PC will harm the PC being grappled?

are their any modifiers to the roll? are grapplers assumed to be prone?

how does one mechanically resolve this situation?

yes if ranged, no if melee

are their any modifiers to the roll? are grapplers assumed to be prone?
