no man.. i think lau lee is a zombie.. they reanimated him
that's why he looks like death warmed over and hasn't uttered a
single thing 
uttered a single thing...?

the last few times he opened his mouth, the other party
member with him have to "repent" for his words 
for all u know, he might be tied to a chair or a bed by the rest
of the gang to prevent him from speaking
