<human>: Some backstory:  My nephew on my wife's side is apart of a custody situation.  My wife and I get extended visits with him courtesy of the boy's mom.  My wife is on the outs with her brother(the boy's dad).  We recently for matters entirely unrelated to the baby or related to why my wife and her brother don't get along, repossessed a vehicle we were letting him borrow.

I'm very concerned he may tell his son that he cannot pick him up anymore because we took the vehicle.  I'm not sure how to approach this subject with him when it comes up.  I'd like to be honest with him(he's 5), but I feel it would be hard for him to understand that his dad made a bunch of mistakes and that's why his vehicle was taken.

Could you distill the essence of the text into 1-3 sentences?
<bot>: Repossessed my brother in law's vehicle, worried what he will say something to his 5 year old son who i'm close with and how I should approach the subject if my nephew finds out about it.
