Yeah im hoping it turns out he setup some sort of trap for agatha where the idea was, if he can get the weasel from her she will be stuck coming back to him and he will use the kings touch to shut her down rather than re-energize her. The kiss he may have turned into a chemical based aphrodisiac to try and make her WANT to stay. And if this is true, he is going to have a VERY hard time convincing anyone involved with agatha to not kill him as soon as possible.
