Now that's a good question, CT. I'd guess that he would have two major moods. First, he would be extremely concerned about the events on Tenebra. The Vasudan massacre, the assassination, the perfect attack on the Carthage and the sniping effort at the Jupiter station are signs that the enemy got a lot smarter. Not only smarter, but manipulative. He knows that the lack of obedience from Lopez was seen and exploited. He knows it because he had also seen it. However, he still has the pace and a lot of new firepower. He is focused on the endgame on Earth.
And he may well be able to guess why Laporte stole what she stole in that defense-tower mission.
This is all we can safely speculate. If we sacrifice "safety", we can further speculate why was he so dead on in his Batman gambit with the Wargods? Why had he been so precise and clairvoyant so far? If you notice, you'll see that only the Fedayeen were able to emulate the kind of wider manipulation that Steele pulled off. But the Fedayeen have a shivan-corpse-super computer. Steele is also Nagari sensitive, aware of it and disciplined; The GTI has had ample access to dead Shivans during both great wars. You do the math.
