Baryl is going to be totally overwhelmed by this, and will attempt to console her. He'll probably panic a little bit in doing so as well, and eventually Stella will come by to give Rarity a Protection Boon to her from Pinkie.

Stella will tell Baryl to tell Pinkie that she should look for healing for herself, for the time being. With a healthy mind and heart, Rarity can help to heal her friends, too.

Baryl will say this, trying to make it sound as good as it did when Stella said it.
