Make the Security Guard Drunk

[mialin8]

I'm stuck at the part where the two younger men are trying to make the security guard playing cards with them drunk. I've figured out that the plugs in the back give hints to the two playing cards. But no matter what I try, none of the plugs correspond with the card the guard is holding up.
I even looked up a guide to which plug hints at which suite. Even when I follow the guide, Duve always says the wrong one.

Did you unscrew the screws in the back wall? (so that the mirror forms a route?)

[Rzep]

You have to unscrew the mirror so its crooked, and the pink heart so its a spade.

Thank you so much! Finally got past that part and finished the game (this first time).
