Iron Man is not fully prepared to fight
Temugin... and thus he falls to the Mandarin's son, whose might is mostly granted by the ten rings of power. But when Tony Stark asks Temugin the reason for attacking the Chinese Embassy, Temugin denies implications and discovers that his right-hand man,
Po, was behind it all. Po stabs Temugin in the back, and before other Temugin men can kill Po, Iron Man grabs him, and flies him to the ruins of the Chinese Embassy in Washington D.C.
After explaining that killing people isn't bad since human lives are immaterial, Po shows a detonator wired to his chest which he is to use to blow the South Korean consulate in New York, and fulfill the Mandarin's dream. But Iron Man disabled it. And after hitting Po, he falls to his knees pray to his wounds.
The F.B.I. and S.H.I.E.L.D. question the Temugin men involved in the attacks, and clean Tony Stark's name from the whole incident. Agent Niel Streich hands Tony the failsafe, and explains that he pushed Pepper Potts to deliver it.
Finally, Tony meets with Happy Hogan and Pepper, and the three of them seem to be at goods again. But Tony is not with Rumiko Fujikawa, who takes off since Tony ignored her all along, and never was the reason of his worries.
Epilogue: Tony meets with Temugin who presents his respects at the ruins of the embassy. Temugin tells Tony that he will seek his death no longer, yet somehow states that he will attack Tony again. Tony decides it's not the time or place to act, and lets Temugin go.
