When Walter had spoken to Anders, he had come off as a sort of an old fashion kind of man. The kind of person who cared about what was 'proper' but fussed over his Pokemon, given how he had named and spoken to them.

Well the latter was true.

It's not everyday you saw a man in a ballroom dress kicking thugs, accompanied by his pink cat practically flying for faces. So Walter felt it best to announce his presence, lest he become a target for trainer or Pokemon's rage.
"A member of Team Valor? I thought you were all in the Radio Tower."
