the very idea that someone could sit down, watch lestat puke while still trying to rationalize the abuse, have a full blown panic attack over it when louis yells that there is no rationalizing this, and then go say it's consensual...that it's not portrayed as abuse...insane...
i also think a lot of people aren't really getting the *point* of louis' reaction. it's extremely harsh and judgmental and completely insensitive to the fact that lestat is being abused, but that is the purpose of it. the entire season is lestat attempting to justify it. this is louis saying that you cannot justify it. there is no rational way to justify that happening. and when lestat has a breakdown over it, they both sort of realize at the same time that this means lestat has been suffering incestuous sexual abuse for 200 fucking years.
it overwhelms lestat, and it clicks for louis. that's when he changes tacts, when he comforts lestat, when he gently tries to help him admit that it's been abuse all along in the bar. it's so realistic, such a necessary sequence.
i think there is unfortunately a knee jerk reaction people have to abuse like this, esp when it's mother/son, where it's just "gross", "weird", or "sick", as louis says. where the child is not taken to be a victim, somehow. i think the show is very honest in having this be louis' initial reaction, until he sees lestat's panic, until he properly thinks it through for a second. and then he gets it, and he feels horrible about what he said. again, it's just all very realistic and bittersweet. everyone involved did an incredible job with this storyline imo.
