in the S1 end credits for the last episode, they intentionally showed an awkward frame that zoomed in on his arm holding a drink and only showed his shoulder and bottom half of his face, but it's pretty much him. the only thing you could maybe claim at the time before S2 aired was that it could be a clone of him or maybe a similar looking family member, but it's normal for a teaser to not reveal everything right away
