Sometimes, desperate times are a plenty good reason to eschew personal boundaries and seek out comfort. A more rested, more vigilant Shinji might be more wary of letting himself get so close without a very good reason for it, but a tired, unwell one won't always hold the same reservations. He may only be very loosely aware that he's even doing it, but it's a brutally honest and incredibly human mentality of 'why bother feeling sick and lonely when there's a solution to at least one of those things right here?' which... it'd probably be completely unsurprising to find out, given how the everything in Havenwell has worked so far, that the gesture is a nice solution to both problems.

As the nap draws on, and the two remain cozied up to each other, breathing becomes easier, those shivers subside, and soon enough, Shinji's fever breaks.

His initial excuses for his condition, though, hadn't been a lie - Shinji really wasn't used to the kind of chill in the air that Havenwell was experiencing. The kind of chill that makes staying in bed under some nice, heavy blankets, curled up with something (or, in this case, someone) warm feel incredibly enticing. It's. Different. But profoundly cozy. Even as the mysterious fever makes its exit, Shinji remains sleeping solidly where he's planted himself.
