It's just as I predicted. Marble, despite his cranky attitude towards Mr. Tumnus when he was a houseguest, now appears to miss the 'Tuminator'. I found Marble all curled up in Mr. Tumnus' bed, and I'm pretty sure he was dreaming of the 'good times' of being relentlessly pestered by Tumnus.
Then again, he might just be saving up his energy for the next visit of Mr. Tumnus. (Avoidance behaviors are energy intensive...)
