In his relationship with Rhodey, Rhodey could be the one who constantly checks on his heart condition and provides practical support, like making sure he has the right medical supplies. This shows the deep bond of friendship between them and how the heart problem becomes a factor in their interactions.
With his friends in the Avengers, his heart problem might make them more cautious about involving him in dangerous missions. This could lead to some arguments as Tony doesn't want to be sidelined, but they're just looking out for his well - being.
It can make his relationships more intense. For example, Pepper might be even more protective of him, constantly worried about his health. Their relationship could have more tender and worried moments.
His heart condition can also deepen his relationships. Since he's facing a health issue, he might become more open with his friends and family. For example, he could share his fears and insecurities with Rhodey or Pepper, which he might not have done before. This sharing can bring them closer together and also change the dynamics of their relationships. It also makes him more relatable as a character, as everyone has some sort of vulnerability.
In terms of his romantic relationships, if a love interest discovers the seal on his heart, it could either draw them closer or create distance. If they are understanding and want to help, it could strengthen their bond. But if they are afraid of the unknown associated with the seal, they might pull away. For example, Hinata might be initially scared but then resolve to stand by Naruto and help him understand the seal.
Well, it could make her overly independent. Since she's being neglected by Tony Stark, she might learn to rely only on herself. She'll grow up faster, taking care of her own needs and making her own decisions without much guidance from her father.
Well, it could make the son grow up feeling unloved and insecure. He might become withdrawn, always seeking approval but never quite believing he's worthy. This could lead to him having problems in relationships later in life, constantly doubting others' intentions towards him.
One interesting plotline could be Tony Stark trying to find a more permanent solution to his heart problem using his own technology. He might experiment with new types of arc reactors that not only power his suits but also heal his heart over time.
His relationship with Pepper could be strained. Pepper might be worried about his health both physically and mentally. She could try to encourage him to lead a healthier lifestyle, which might lead to some arguments as Tony is used to his own ways.
His sense of humor would also play a role. He could use it to lighten the mood in tense situations within SHIELD. However, some agents might not appreciate his wisecracks all the time. For example, during a serious mission briefing, he might make a joke that some of the more serious - minded agents find inappropriate. But on the other hand, it could also help relieve stress for others.
With Sasuke, it could either drive a wedge or bring them closer. If Sasuke blames himself for Naruto getting injured while protecting him, he might distance himself out of guilt. On the other hand, it could also make Sasuke realize how much Naruto means to him and he could become more committed to their friendship.
His apathy can strain his relationships. His friends might feel neglected. For instance, Sakura could be confused and hurt as Naruto no longer shows the same eagerness to be part of the team.
He might try to self - medicate at first. Maybe he takes some experimental drugs he's been working on in his lab. After all, he's always been one to take matters into his own hands.
