Pietro got excited with this goal, he definitely didn't want to die hit by bullets, even if he had to save someone, so reaching Mach 4 speed was the training goal.
"Remember, I'm training you to be a hero, so don't be an idiot and sacrifice yourself to save someone. If you can't save a person, don't die for it. Think that you have your sister to take care of, and you're strong enough to save many people in the future. Let one die and don't sacrifice yourself." Jack said.
"I understand, I won't waste my life easier," Pietro said, keeping Jack's words in his heart.
"Very well, I'll demonstrate the Mach 4 speed you can achieve. Try to follow me with your eyes." Jack said and then disappeared at high speed. He ran circles and loops around the place he created, leaving trails for Pietro to see.
Jack stopped and saw Pietro shocked. He didn't know that Pietro's training goal was something Jack was already capable of. Jack running was much slower than flying, after all, he had to use his legs to run and avoid breaking the ground while running.
But at least once, he had to show Pietro how to run. Jack could use a speed several times faster than this currently, but that was not necessary, and Pietro might not even see him running.
"That treadmill was created for you. You can run on it to increase your stamina and endurance, so you won't get tired easily while running. When you can run for 1 hour without stopping at a certain speed, you can increase your speed." Jack said.
"I understand," Pietro said and started training.
Jack remembered in the movie that after running at maximum speed for a while, Pietro would quickly get tired and put his hands on his chest after running for a few minutes he had his hands on his chest, so building up stamina was more important than running fast.
That's why Jack was lucky that as his strength increased, his endurance and speed increased too, so Jack would never have to worry about it, even when using the Raiton Chakura Mōdo or opening the Inner Gates.
Wanda was happy to see her brother improving and continued to train herself. Kitty also started training her skills so she wouldn't be left doing anything, only Anna was bored, but Jack sometimes kept her company.
Soon Wanda improved a lot in her training, and Jack also improved while watching and training Wanda. So he felt it was time to solve Anna's power problems. He called Anna, Kitty, and Wanda into the Mirror Dimension for this.
Jack knew Kitty was reliable and she could watch. He would solve Anna's problems, and Wanda would watch and learn what she could do in the future. As soon as they all arrived, he looked at Wanda and Anna.
"Wanda, I said that my powers and yours are similar. While I help you train, I can also improve my own powers. So today, I'm going to show you what it's like to change reality to the extreme," said Jack.
"Anna, I've spent the last few months studying how I could do this in an effective and safe way for you. Now I'm fully confident that I can allow you to completely control your powers, so you can touch anyone in the future and activate your powers only when you want to," said Jack, smiling.
Anna and Kitty were shocked to hear this. They had seen Jack's powers, but they never imagined he could change the powers of mutants. If this were true, then perhaps Jack could even take away the powers of other mutants.
Now they understood why even though Jack trusted them, he made them sign a magical contract. After all, his powers were much greater than anyone thought. Anna was happy to know she could control her powers.
She was happy and conflicted about it, Anna had already decided she would break up with Jack when they returned to New York, and now he was giving her the thing she had always dreamed of.
Anna understood how Jack must have thought and trained to do something that even she thought was impossible. If it were anything else, Anna might have refused to avoid feeling more guilty, but controlling her powers was something that only Jack could help her with.
Anna thought that Professor Xavier had helped her several times and she was just grateful, so she would also be grateful to Jack for helping her control her powers and would not stay with him because of it.
"Thank you so much, Jack. You'll be fulfilling my biggest dream after helping me control my powers," Anna said, crying with joy and guilt.
"Don't worry, Wanda, look closely so you can learn," Jack said.
Soon Jack had to focus very hard on his magic and on controlling the reality stone and the mind stone. Jack first controlled Anna's powers with the reality stone and his magic and then unlocked the mental blocks she had with her powers.
Thus, Anna's ability to control her own blocked powers was increasing. The reality stone kept her powers under control, so it took a few minutes for Anna to control her powers.
Without the reality stone, Anna would have to improve a few more times to control her powers and could even kill someone while doing so, but Jack managed to keep Anna's powers under control, so she wouldn't have mental blocks and could continue to improve.
Anna had her eyes closed and felt the changes in her body. Kitty watched everything with curious eyes, and she was excited for Anna to be able to control her powers, and Wanda was the only one who could see what Jack was doing and tried to learn something.
Soon Jack sighed, and Anna opened her eyes. Her eyes shone with yellow, then red, then back to normal color. Anna knew something had changed, but she didn't know if she could control her powers now.
"I did it. Now you'll always be able to control your powers, Anna. No one can mess with your mind or lose control of your powers. With time, you'll get better and stronger with your powers. You can touch Kitty to see," Jack said happily.
Anna still couldn't believe it took only a few minutes to fulfill the dream she had always had since awakening her mutant powers. Kitty approached Anna, took off her gloves, and touched her hands.
