Julien would be good at Interference or Exploration if he had like any night vision anymore. Yuuya's skillset fits pretty well.

...but, he doesn't. He wouldn't be helpless, but he'd have to be led by the hand whenever things were particularly dim. I can't echo him back Yuuya's night vision glasses yet. They're too small for him. And anyway he's fumbled around in the dark before.

Mission control, then! He can think fast, sometimes. Maps... Maybe.
