IGH. Three little letters, but they could have a huge impact on the future of Jessica Jones. So what exactly do they stand for? It's not exactly clear, although it obviously refers to an organisation who are involved in experiments on or leading to gifted humans. It's the private organisation who Kozlov worked for, but they don't actually exist, at least not officially. It's later revealed that they're the ones who covered Jessica's medical bills after the accident. It looks like it could all be linked, which will be fascinating going forward. Just how much has IGH influenced? There's Jessica, there's Simpson (no Jessica Simpson related joke intended...), and it wouldn't be too much of a stretch if it's revealed they were involved in the experiments by Kilgrave's parents as well. Finally, what do those letters stand for?
