Actually, I kinda like Fan's idea of the RT getting boarded, if we combine it with the 'he can float like a butterfly, sting like a bee, but eventually he'll screw up'. Putting the SC Agent in direct, personal danger, whether it's permanent or not (for all the Culture knows, Chaos can fritz a backup if they have the 'original' in hand) could be the impetus for her to break out the serious skillz and whip the boarding party's collective butt. The RT gets away - maybe throw him a bone by getting in a lucky shot at the Grand Cruiser, and the remainder of the fleet turns to infighting to sort out the new pecking order rather than pursue the injured light cruiser. But she's blown her cover completely at this point, and as usual, hilarity ensues.
