This question about training was asked form Gojo even if question was about Arc.
'Why am I even here if these two were going to talk to each other? Is powerful people slow in their head.' Arc was feeling it hard to pass his time here as those two person in room have started to talk to each other.
Arc have expected that he would be questioned a little with having to make a conversation with them but his his mind monologue that he prepared have gone to waste.
In time of few minutes that talk between the Gojo and his grandpa have ended as he was made free to go. Arc could not go back by himself because he can't exactly remember the way back so Grandpa called the butler to help the Arc go back to his room.
