Reactions of Swede and some doubts

I think Swede was afraid to show his face anywhere near any of the old gang, as he was the one who Kitty duped into ripping off the gang at the farm. He knew even looking for Kitty after she split would be trouble, as his old cellmate Charleston had warned him about her deceiving and self-serving ways. Swede even mentioned Charleston's name during his last breath as an acknowledgment of the old guy's warning. As for why he chose not to run, he was tired of running and hiding and had had enough of the lot of it!

What I question about the film is why none of the gang smelled a rat when Swede showed up at the farmhouse? Even Colfax said: "you're here, ain't you?" when Swede accused the lot of them of double crossing him. Therefore, someone on the inside had to tell Swede about the farmhouse, and why not suspect the "dame"? They all knew Swede was totally under her spell, and would roll over for her in a hot minute! They all also knew she was under Colfax's control so why not suspect Colfax and her of collusion in the duping of Swede and the rest of the gang?

Lastly, Kitty was so self-serving and rotten, she tried to coax her dying husband into lying about her complicity in the robbery, a fact best illustrated by Lubinsky's comment of "Don't let the man tell death-bed lies that would damn his soul!" or something close to those words.

Anyway, that's my take...hope this helps!
