>>4258652No yeah I agree with your interpretation as well, I'm just saying
>>4258018 has a credible enough precipice for Misato knowing what Shinji did in the hospital room, since we know a video feed to that exact room is running at all times. It's more than likely one of the other staff like Hyuga, Aoba or even Maya could've seen it as well, but Misato is also included in that pool since she basically runs Central Dogma and had asked for a visual check on Asuka's room before.
In reality your interpretation seems to be the far more likely one as well as the one most people tend to make when analyzing why Misato gave him that incentive kiss before dying, and like you said it's backed up by what we see in instrumentality later on as well.
