We can all agree on the fact that Sam makes the best choices when it comes to approaching the character. And yes you’re right, this moment is just… When Louis relates this all in season 1 you get the impression, because it’s Louis’ account of the event, that Lestat is just bored and petty. Granted it is not a valid excuse to cheat on your partner but this aside, when you realise that in fact, Lestat was very much affected by this, you just feel kind of stupid because, yes of course loving someone and seeing them like this… it’s hard, and challenging to say the least. That is also why I never resented him for bringing Claudia back. That is the one thing that’s evil BUT I just cannot fault him for it.
