Except that picture is probably in no way related to Heroes. This may come as a shock to you guys, but Zachary Quinto does have other roles, and maybe on real life occassions has the need to wear a tie and dress shirt
But seriously, if that is from Heroes, my guess is it is from his brief stint working for Prima Tech, where he dressed like HRG.
But yeah, 5 Years Gone won't happen. Too much would have to change...you'd have to give Parkman a believable reason to become what he is fighting against this season, for example. The writers are terrified to change the status quo of this show...do you really think they'll do such a game changer?
