The Man They Called a Magician - S1-E2
Plot hole: Lupin was knocked out by Pycal when he shot him with a gun at point-blank. On the other hand, the 'shield' he used was strong enough to not even budge when Jigen's gun and several machine-gun shots would hit, and sustained the impact of an anti-tank rocket, so the dampening powers of the chemical are pretty inconsistent. It's also completely impossible that it works as shown, unless it also coats the mouth, the nostrils, the eyes.

The Man They Called a Magician - S1-E2
Other mistake: Despite falling unconscious at the bottom of the sea in his car and being rescued by Jigen, with Pycal within range since he got out of the car at the last moment, somehow Lupin gets to Pycal's home before he does, setting up a bunch of tricks in advance too.
