Once upon a time, Hughie and Victoria found themselves in a rather strange situation. They were both on a mission to expose a corrupt supe. Hughie was his usual nervous self, but Victoria was determined. They sneaked into a Vought building, hiding in the shadows. Hughie accidentally knocked over a small object, making a noise. Victoria quickly signaled for him to be quiet. They continued on their way, finally finding the evidence they needed. It was a long and dangerous journey, but their friendship grew stronger through it all.
One common theme is the power dynamic. Given the nature of 'The Boys' universe, exploring how Victoria's power and Hughie's more 'ordinary' (in comparison) self interact is popular. For example, how he copes with her abilities.
A good plot could be that Hughie and Victoria discover a new supe who seems to be different from the others. This supe claims to be against Vought's evil ways but is being hunted by Vought anyway. Hughie and Victoria have to decide whether to trust this new supe and help protect them. They go on a journey to find out the truth about this supe's origin and intentions, all while avoiding Vought's traps and attacks.
