Rush calls his bluff without even questioning it - no, he won't kill Asadi, and no, there is no one coming to provide backup. That's all right. He throws the woman aside hard enough that she is left winded and struggling to recover herself on the floor; he uses that momentum to turn himself into Rush just as the collision comes.

He goes down hard, Rush atop him, teeth bared like a wild animal. His hands are around Gus's throat and Gus strikes back unrelentingly, one hand going to his throat and pushing back, the other dealing blows to his gut and anything else within reach. Break a rib if he has to. Rush's grip does not yield but Gus will not surrender easily, not now, not after everything. White got the better of him and for that he has been sent here, stranded in some strange, closed off variant of Manhattan; he will not let this happen again. White outsmarted him; Rush will not overpower him.

He twists his body forcefully, aiming to dislodge Rush's iron grip, aiming to get on top. Kill him, like he should have done before.
