I dunno... Assuming it's indeed what he asked Pikachu doesn't seem bothered with it so it's ok, I guess?Also, now that we know Pikachu’s past, the Detective’s “How’s your Mom” question kinda hurts. “How’s my Mom? I dunno, I left her and my sister in the middle of the night without telling them. You got any more Poke’chow?”
Also, while for us Kanga looked a mommy, it might be the case of Pikachu seeing them as just very caring friends. Considering how young he was back then and he was pretty much lonely, it wouldn't surprise me if he didn't understand the concept of "family" the same way Ash doesn't understand "romance"
