Check out the 30 second preview for Wednesday’s Arrow episode, titled “The Undertaking.” There will be flashbacks, but from what we can gather, they are from before Ollie gets stranded on the island.
This episode will have guest stars Jamey Sheridan (Robert Queen), Colin Salmon (Walter), and über fan favorite, John Barrowman (Malcolm Merlyn), however, the preview doesn’t dare spoil it for us by showing them.
Thanks to GreenArrowTV for the heads up.
