In Black and White versions, Cheren and Bianca had preset names; therefore you couldn't choose their names. However B2W2 allowed you to name this guy:
"I'm about to unleash my rage because you gave me such a dumb name!"
So what name did you choose for Hugh? I named him Patrick the first time I played W2, then decided I didn't like him so I named him Fart the second time around because I was feeling immature. The third time I just named him Hugh.
