My favorite part of Lost Tomb 2 is Zhang Qiling in episode 1 in disguise as a loud, overly-familiar, balding, middle-aged man, just yelling his ass off all over the place.
Because it means that in the canon of this story, Zhang Qiling is capable of imitating annoying old men, and I choose to believe that he is just mentally like "This is how all humans speak and act."
But also the way "Consultant Zhang" clings to Wu Xie and Pangzi immediately like "HELLO NEW BESTIES"... and then refuses to let go of Wu Xie's hand until well after it gets awkward (probably so Wu Xie can feel that two of his fingers are too long and he'll realize it's Zhang Qiling but still).
"Can you imagine? One day you suddenly wake up in a cave and look around without knowing anything, but you already have a responsibility that you must shoulder. You have no right to see the scenery along the way, and you can’t enjoy your friends and lovers. The moment you regain consciousness, all the beautiful things in your life have no meaning to you.
Zhang Qiling is carrying his own destiny in silence." (DMBJ Volume 8, Postcript)
