I would hope that in this situation the controller would, at the same time as the go around instruction was issued, be instructing the Ajet to stop; to cancel the takeoff clearance.
That would be reasonable.
It would also be reasonable for the controller to have a plan B of what needs to happen if the Ajet does not/can not abort, and to communicate it to the crew of the Cjet at the time the go around is issued, if not earlier. (He/she has only had about 2.5 minutes to think about it.
)
(Actually that would be plan C, by then, wouldn't it?)
And if these instructions aren't forthcoming in a timely manner, it would be utterly reasonable for the crew of the Cjet to take whatever action was felt necessary to avoid a collision, be that a turn, or even just a bit of an offset/sidestep.
I get the feeling you aren't asking just out of academic interest.
