The two actors exchanged pleasantries while Willa Holland, who plays Stephen‘s sister and Colton‘s girlfriend, stood by.
“Just shook Roy Harper’s hand,” Stephen tweeted.
Colton added, “Oliver has a very firm hand shake.”
Stephen wrote just the day before, after the cast and crew had wrapped, “What a sterling day by the Crew & Cast of #Arrow. Saturday was at our mercy.”
