Mingyu and Five intend to corner Haltham if possible and ask the following:

1) Why have you been lying to us?
2) Who are you, really?
3) What are your motives?/What do you want?
4) Why should we believe you now?
5) Why did you set us up?
6) Give us one good reason not to fuck you over for all the deceit.

Mingyu will be doing a very hurt and betrayed friend thing which is, to his dismay, only halfway an act. Five will be agitated paranoid bad cop.
