Interestingly, a comment on the Team Wallace page seems to be addressing Elisa directly (talking about how they always enjoyed watching her compete Johnny) and said:
I don’t believe u would have supported Briggs competing Corture at this level if they were no sufficiently prepared and capable of completing without injury to either of them.
Elisa’s full response to the comment (from her personal profile) was:
hiya! I competed Simply Priceless aka Johnny. Team Wallace is my dad(Rick Wallace and Briggs Surratt) and I’m Wallace Eventing.
There does seem to be an effort to move away from a “Wallace universe” and maintain two separate online personas.
