For brief context as Wheeljack describes it in this issue, Shockwave quite literally almost destroyed the universe in the "Dark Cybertron" plot. Ironhide had gotten a glimpse of the future which does not end quite well so he's in a rut now. He despairs over the loss of the surety in the future that the vision had granted him, but with good humour, Wheeljack tells him that that state of uncertainty is just called "being alive".

With that said, he's not quite the chipper battle-ready G1 self and does not emote much in the few pages he's in. I'm just looking for a deep, voice with that Peter Cullen G1 southern drawl still, or you can also go towards Jess Harnell's performance in the Bay movies! But again, don't feel the need to directly do a 1:1 impression!
