Bolstered by his own confidence and this ever-present steadiness from his father, getting through the pandemonium still proves difficult, though not nearly as hard as it might've been if he'd faced it himself. Truly tethered to Wei Wuxian in that moment, Sizhui understands his strength, accepts when it is imparted and attempts boosting his own encouragement in even a half-chance it might match. (It does because it's what he wants, but Sizhui's too focused on Wei Wuxian's support and ignoring everything that's desperately fighting to keep him in limbo.)

The fogs grow thicker, the lights are almost blinding and those murmurs are deafening, but Sizhui winces and— silence momentarily falls over them.

Once his eyes reopen, there's the Voidtrecker Express in all its glory, looking just like he remembers leaving it the last time. A sudden inhale, something that comes out as a quivery sigh then his other hand moves to grip Wei Wuxian's forearm and he halfway slumps against him, barely managing a quiet thank you without shaking again.
