Six Forgotten Warriors Chapter 2: Unclaimed Legacy - S5-E3
Other mistake: When Silver Sable infiltrates Kingpin's Russian lair with sleeping gas, before falling unconscious, Kingpin correctly deduces that he has been betrayed. In the next scene, Kingpin asks Silver Sable how she was able to infiltrate his lair, and she tells him one of his men is a traitor, which elicits an incredulous reaction from Kingpin, completely contradicting the previous scene where Kingpin already surmised there was a traitor.
Answer: I believe it was just a way to try and show the suit is "oily" or reflective. It also helps define the character's features since otherwise, he'd just be a flat black color. It's similar to how the black suit Spidey had blue outlines. (I don't know why they chose a pink/red color... maybe because red is associated with power/fire/war, so it's a more "evil" color?)
