[He doesn't immediately respond, although he's more than aware that Tony is there -- and perhaps willing to dismiss it because it is a dream. He hasn't yet locked onto just how much Tony really is in this dream, literally, but if he's bothered that Tony doesn't quite 'fit' into the scenario that's playing out, he doesn't show it on his face at all.]
... Nah. [Not much to offer, after a moment, but he's clearly distracted by the dream itself -- even if being made aware of Tony's presence means the dream is shifting around, going fuzzy in places and fading from view... not too long after, the sound of the rain disappears, even if it still is, technically, raining on everything but them.] Hitting me's not gonna do a damn bit of good with this.
