Two questions about B2W2's Hidden Grottos?

Question

First: Can Pokémon in hidden grottos have non-hidden abilities?

Second: Does the "Met at" location mention that the Pokémon was caught in the grotto, or does it just say the Route the grotto is located on?

Thank you in advance.

Comments

You should ask these as two separate questions.

Doesn't appear like they can. Source: https://www.serebii.net/black2white2/hiddengrotto.shtml
