Series 9 Episode 7 discussion

[HellsBells]

I have some questions concerning 9.7.
1) At the beginning after Harry and Lucas get back from seeing Vaughn, Vaughn calls Lucas and the Chinese are listening in, do the Chinese then make a phone call and speak french ?
2)Is Vaughn in love with Maya because I think he was genuinely protecting her from the Chinese and still had her photo ?
3)How did Lucas find Vaughn and Maya, what people did he speak to that wouldn't speak to Harry?

Off to change my signature now because I think we might just find out what Harry will do to Lucas if he's lying !!
