Watching the live stream & in person, I had the same thoughts. I wasn’t sure I supported them letting him continue to run, but glad I was in agreement with the officals.
I also saw Bronte run past me (in person) & thought he looked tired. I was telling my SO with me that I thought Emma would pull up if she felt the horse was tired because she had done it in Maryland in the past, but she didn’t. Also glad I agreed with the officials on that one, but wished they would have pulled her up instead of letting her finish - because she could have had a bad fall. TBH, I didn’t see the horse jump more than 1 jump, but looked tired going up the hill to stainability bay area before getting to the last combination. (I was listening to the announcer hoping for the best news & was delighted when I heard she had finished because that meant she was safe…)
