Tony wishes there could be something he could do or say to soften the blow, but he knows it's impossible to. He can't even imagine how Peter must feel, knowing he lost all this time. Maybe he should have just re-set the timeline, bring everyone back to the past right after the first snap, but selfishly Tony hadn't been able to agree to that.
