How do you think Flash felt?

During Forgotten Friendship, we saw him for a  brief moment, as Sunset ran out in front of his car, and the whole memory loss scene with Wallflower, presumably played out in front of him, along with Sunset's friends.How do you guys think he might've felt, seeing the girl he once loved and dated have her friends' memories ripped from her, one by one, until she had mentally reverted back to a pony fresh from Equestria in a strange world?

He wondered what's for dinner.

He probably viewed her the same way that everyone else did as a result of Wallflower's abuse of the Memory Stone.

Flash would've seen Sunset as the bully she formerly was, like everyone else who had their memory wiped.

Flash didn't look that concerned. if he was concerned, he would have at least walked up to them and asked questions. he was just driving his fancy car on the school parking lot
