The parenting plan always reverts to the other parent unless there is danger to that child. That is why the child was not allowed to stay with you while he is gone. However, if there is a hearing did someone request that the primary custody change over back to the mother? Is the 6wks only temporary -one time thing or will this continue? If it continues then it is possible they will revert to the mother as primary custodian because moving the child back and forth will be too hard on them. (Remember the child cannot stay with you...if the mother wants him) so ...if this was a one time training course..then I think you should be fine with keeping the child. Although I am curious as to why there is a hearing.
