Want to do me a favor? Well, it's not exactly a favor since I'm sure you won't mind your end of the deal, but... How about going out with Hector the night of the 21st so I can spend some time with Lacroix? It's my birthday that Saturday.
So... how about convincing Hector to visit you for the night sometime? So I can talk to Lacroix without him worrying that Hector's going to walk in on him.
It's a win-win for everyone, right? No harm done. But Lacroix seems to think that Hector lacks... initiative? sometimes, so maybe it'd be a good idea for you to ask him.
