[ElProximo]

People, this not complicated:

He was very very angry. built up frustration firing up into intense anger.
and,
The only 'faking' was (and Bea calls this) is that he is desperately determined to prove to everyone he is not the sort who is easily upset, he is a hippy love type who doesn't get angry...
...yet.. anger.. building... GRRRR.... must cover it up, literally with hands and blankets.. must say its something else... must just try and act.. calm GRRRRR.

Anger. He is full of anger and rage and he most definitely has it saved up inside for Bea.
