Very true. It's not as if either of them are particularly eager to sit down and spill their emotions at any time. It usually looks incredibly painful! The events of season one kind of forced them into a place where there was no way to get what they wanted without a little emotional honesty after a lot of years of lying and deception and I'm sure it had to feel like such a relief (especially to Philip!) for things to just be okay so they could go back to just getting what each other meant, something they're actually good at when they're not actively lying, and away from the whole having to spill your guts thing, which for him is just sheer torture.
