The blows hit but seem to do next to nothing. However, Caitlin is not surprised since Selebrity is correct, she is holding back since it's a training session and she doesn't wish to hurt such a handsome fellow. Good on him for smiling, though. He takes it all in stride but at the same time he gently scolds her for fighting more like the famous Muhammad Ali rather than fighting like how she should be. The words the A-lister uses do sound harsh on the ears, like sandpaper rubbing on wood to scrub away the rough spots. But that handsome face speaks of a different story since he doesn't look furious at her or anything other negative thing. He's instructing her that she can do so much better. He's a teacher who is trying to raise her above her station. But he can only open the door, it is Caitlin who has to walk through it. At least, that's how the Ultra Amazon takes it all. Suddenly she feels a bit like Neo in the Matrix movie and Selebrity is Morpheus, trying to unlock her potential. The difference, though, is Caitlin is certainly not 'the one' and she isn't anyone special. That's Selebrity, the man of might and right. A star and unofficial king of Hollywood. At least, to Caitlin he is.
Caitlin sees he has more to say so she waits and listens. Then he does that dirt thing, lifting a mighty chunk of it like it weigh's nothing at all. Treating it like a feather before breaking it apart as easily as he would tissue paper. The strength to do that is nothing but impressive as she takes a shower of dirt and dust. Out of habit, Caitlin brings up her hands as she closes her eyes to prevent anything from getting in. She fully expects an attack. But she slowly opens one eye and sees the dust settle with nothing coming. The Ultra Hero lowers her arms.
Caitlin coughs as the last of the dust clears before she listens to the rest of what he is trying to get through to her. When he finishes, Caitlin glances at the wall he says one of them will go through. That's a big wall. Before, she held back because she didn't want to hurt him. But Selebrity wants to see what Caitlin can do. Unleash all she has and fight like someone who has powers, not like a boxer.
With only Ultra Strength and Ultra Invulnerability in her corner, Caitlin can only do so much. She lost the other powers she once possessed. But even with what she has, she can still do plenty. Plus, her greatest asset is her brain. He even pointed at the side of his head, indicating he wants her to use it. Not a bad idea at all. With much of her power gone, she will need to think.
Caitlin does think, but only briefly as she gets the spark of an idea. But suddenly she moves quicker than hurricane force winds as her powerful arms slide through the air like a pair of swords. Two hands clap together, resonating with the sound of thunder. This close to Selebrity, the sound propagates through the air at him in less than a second, reaching his ears like some invisible invader ready to do it's work. The sound that Caitlin creates from her clap is off the charts as no instrument can measure it. And as it reaches Selebrity's ears, it is Caitlin's hope that it causes the man to clap his hands over those ears of his, to distract him with the pain. It's an attempt that Caitlin hopes succeeds because, on top of it all, she also tried to do it unexpectedly. As per his instructions, Caitlin is trying to be unpredictable, hence the sudden thunderclap.
Provided the thunderclap works and Selebrity is effected by it to her satisfaction, Caitlin tears up the ground as if it's made of fragile Styrofoam in order to pick up a large boulder of dirt and rock before she launches herself at him through the air with such speed as to leave even a bullet train in the dust. Her arms come down to try and smash the dirt boulder into his face as part of her next attack phase. If he even thinks to open his eyes, it is Caitlin's hope the breaking up of the boulder, dirt and dust get into his eyes, nose and mouth in an attempt to not only blind him but choke him.
The final phase of her three pronged attack, provided the first two are successful, Caitlin then seeks to deliver such a mighty right hook as to lay waste an entire mountainside as an attempt to land a blow with such devastating force as to perhaps get him to go through that wall he warned one of them would go through earlier. Afterwards, if all goes according to plan, Caitlin waits to see what he does next OR if any phase of her plan fails, to be on guard for his counter offensive.
