His family would be extremely worried. Scott, as the eldest, would likely take charge immediately. He'd be focused on getting Virgil the best medical care possible and coordinating with the rest of the team to ensure his safety.
Maybe Virgil's injury affects his ability to perform his normal duties in future missions. This could lead to some self - doubt and a struggle to regain his confidence. The other characters would then have to support him both physically and emotionally, like Scott giving him pep talks and helping with his physical therapy.
One common theme could be the other characters' reactions to Virgil being hurt. For example, how his brothers might step up to support him or take on his responsibilities. Another theme might be Virgil's own struggle to recover and get back to his duties.
You can try looking on fanfiction websites like Archive of Our Own (AO3) or FanFiction.net. There are often many different Thunderbirds fanfictions on these platforms, and you can search specifically for ones involving Virgil getting hurt.
One idea could be that Virgil is kidnapped by an old enemy of the Tracy family who wants to use him as bait to get to International Rescue's secrets. Another could be that he's abducted by a group who mistake him for someone else with valuable knowledge. Maybe a mad scientist kidnaps him to force him to help with a dangerous experiment.
The motive could be ransom. The kidnappers might know that the Tracy family is wealthy and figure they can get a large sum of money for Virgil's safe return.
Jasper would probably be on high alert, using his ability to sense and manipulate emotions to keep the family calm while also being ready to defend against any further attacks. Rosalie might be angry and vengeful, determined to find out who hurt Esme and make them pay. Emmett would be protective, standing guard over Esme while she recovers. The family as a whole would be in a state of shock and concern, their usually peaceful existence disrupted by this event.
Macgyver would probably be very worried. He'd quickly assess the situation and try to stop the bleeding if she was bleeding. He'd use his resourcefulness to make a makeshift stretcher or bandage.
His friends would be extremely worried. They might immediately drop whatever they are doing to rush to his side. For instance, Thomas would be right there, trying to assess the situation and figure out how to help. He would be filled with a sense of urgency and determination to get Minho the care he needs.
Leo would likely take charge immediately. He'd assess the situation and start giving orders on how to help Mikey. He'd be calm on the outside but worried on the inside.
Alfred reacts with calm efficiency. He quickly assesses Batman's injuries and starts to take care of them. He doesn't panic because he knows Batman needs him to be strong.
