Part one- caught?

Virgil, though he protests acting like a toddler at times, is in fact a little. Obviously his anxiety refrained him from telling the others as he feared there reactions. Virgil regresses either from stress or for fun, but he always does it in his room with the door locked. His regressions are happening more often. After the episode "Are there healthy distractions?" Virgil has to excuse himself, falling into little space, but when morning came the side notices a mistake he made last night and the others find it.
