There's some lessons to be learned here by both you and your partner.

The touch at third is your responsibility, therefore it's your call on an appeal.

As Cecil said, I would make sure that everybody knew that we had an appeal for the runner not re-touching third on her way back to second and that you were upholding the appeal and the runner was out.

Your partner should not have said anything, and if he had a question about what was happening, call time and come talk to you in private so you're both on the same page.

Your partner's actions probably made it appear that he didn't have confidence in your ruling and was making sure everybody knew it...all this is going to do is provide ammunition for the next time one of the coaches doesn't like your call and tries to work your partner against you.
