Snart barely smirked, looking a little too out of it and far paler than his usual fair complexion. "...told you. If Mick can do it, you can too."

Oh, he loathed being carried, but he knew that was literally the only way he was getting back to the ship alive. By the time Matt made it through the Waverider's hatch, Gideon alarmingly reported Leonard's condition.

"Mister Snart's internal organs are already shutting down. His blood-pressure is crashing and he's going into shock."

In no time, Jax and Martin were helping Matt get Leonard into medical. Fortunately for Leo, Gideon already had an antidote for that particular poison in her database, synthesising it took seconds. From there, saving Snart's life was as simple as reversing the damage. Okay, not so simple, but for Gideon, it wasn't any more difficult than regrowing a limb.

When he woke, everything was too bright, too loud, and his skin was too sensitive. But at least he woke up. "...next time I decide to get hit by a train, I'd appreciate it if someone would shoot me instead." He ground out from the medical table, eyes still shut because it hurt to open them. All he could see was blinding white when he did.
