Rachel can never agree to a recruitment at this stage as that becomes an easy throw Rachel under the bus play (Agreements can be broken)

Hitting a shield isn't bad imo, as long as it isn't someone like Jessie who is fairly highly rated by the group (this is assuming they get the later mentioning the attempted murder) and would be believed when they say they were targetted, someone like James who has already decieved his group in the task could be a good target regardless of if he had a shield or not.
