Who were the men in the Warwick teaser and what exactly did they do to piss off Warwick Riot?

Warwick was pretending to be Red Riding Hood's grandmother, except he got so immersed in that he started to actually believed he was her grandmother. And when Red came along with her basket of goodies, so did Fleg and Boggin who stole the goodies and ran off to Zaun. Warwick, having previously been excited to try the scrumptious baked goods became infuriated at the the theft and gave chase after the Zaunites. Of course the two dropped it during the chase. That's why we don't see them with the basket of goodies.

Stole his Beggin' Strips.

WW realized he's finally getting a rework and pissed because it took them so long. : ^)

In the beginning, one of them said, "I told you this was a bad idea." This could mean two things.

1. They're thieves and Warwick is a monster, that is trying to do some good.

2. Warwick is a serial killer and those two were trying to kill him.

1. Expendable plot devices
2. Bled all over

My guess is Singed used them as pawns to try and find out Warwick's location/hunting habits and it ended up getting them killed.

"In Zaun’s Gray-filled streets, the criminal underworld is hunted by an engineered beast." Probably just normal criminals, one of them being augmented. They probably just entered his hunting grounds for their criminal activities and gave no shit about him already killing people there, that's why Fleg says "I told you this was a bad deal man." because Boggin wanted to go there anyway.

RIP Graves' chunkier brother.

My theory is that this teaser happens after Warwick destroyed Singeds lab since he seems complete. As time went rumors began to spread about a beast in a certain part of Zaun away from the main parts and both Boggin and Fleg were paid to hunt this "beast" down. Judging by the teaser things didn't go as planned XD
