I really enjoy how they handle Zhao Yunlan's dawning comprehension too. And how he definitely gets very frustrated with Shen Wei, but is also not willing to push Shen Wei too much and make him tell him because he can see how Shen Wei is struggling with the whole thing.

My favorite thing about the scene with the alcohol (this is when they're off in the "wilderness" right?) is that Shen Wei only drinks it because he can see how ZYL is being pressured into drinking when he doesn't want to keep doing so. Even though it leaves him totally defenseless and ZYL can pry into what he's trying to hide, Shen Wei isn't willing to let ZYL suffer.
