If you really must be a troll, install a keylogger onto his computer. BUY beyond keylogger or another reputable keylogger. Don't google "keylogger" and then download whatever you find, you will get a virus.

I am a network engineer and I caught an x-girlfriend cheating this way. Being able to take chat logs and throw them in that lying b*tch's face was the best.

You will have to install it on his laptop when he is not looking. That requires stealth.
This is really the only other option other than hoping that he accidentally leaves himself logged in.
