Yeah, we were all freaked when it happened- he put his foot out while passing a tree and nearly destroyed his leg as a result. I wasn’t there but my neighbour told me about it just after it happened. IIRC we were about eight years old at the time- we were in third grade.
Yikes!
Hubby reminds me that he was in season 1 (I think) of Person of Interest. He was introduced as a mild mannered fellow, but we found out that wasn’t the whole story.
