It was said that Sheerah and Batman had a little "secret" thing. The tycoon who was Iron Man had been fond of fooling around with cover girls in the past, and that naturally included the main supermodel for Victoria's Secret every year.
Although the tycoon no longer did that, letting people make the connection wasn't a bad thing.
Victoria's Secret had already sent out the invitations; Tony not going was understandable.
If he did go, the news reports wouldn't necessarily be logical about it.
The Bat/Iron CP matched with a singer + supermodel duo would be too perfect.
But for Luke, Sheerah's appearance wasn't important. What was important was that his sister Claire was here as well.
Looking at Claire, who had now become a college student, Luke caught her up with a smile and spun her around before they headed for the parking lot.
