Dany's Assassination Attempt

With how the show implies it, Varys it would seem genuinely was willing to kill Dany (of course he didn't know that Viserys was dead at that time), and that it's because of Jorah's choice that Dany lives at all--giving his character motive and empowering his actions. This is a good thing, but I'd argue the book's version of events are a bit more complicated than that.

Thoughts?
