The context of the following conversation is Robin was concerned their Kai was smoking drugs so when Kai left for school Robin entered Kai's room to search for evidence.:
Kai says I don't know why but the way Robin's eyes looked I knew she was up to no good..
The friend responds What do you mean?.
Kai responds For the past couple of weeks I had a feeling she was smoking, the way she responded and the extra laziness. So I decided to check her room when she was out...
The friend responds That's horrible! Did you find anything?.
Kai responds Luckily it wasn't as bad as I thought. But not too fond of this "vape" thing, gonna have a talk with her..
The friend responds Good luck, she won't be happy that you sunk in her room, kids these days and their innovative drugs....
