#109 - Aftermath - in A Cabin In The Woods
Tony's just grumpy because he didn't get to eat after all that. I'm sure you can gather from context that by this time, there's been quite a few nights that end with Zeno in tears and his friends trying to comfort him.
Zeno would have been fine staying behind with Menu-- his inclination to protect Zeno overrides his lunacy during the full moon. Zeno just finds it a little awkward when his wolf friend is being weird and feral, eating absolutely everything.
