>all of this shit
the whole thing have two main components, the boy are confused seeing her mom at his same age so he doesn't really know how to treat her (AKA as his mom or as a woman) and two, he's clearly gonna be a early blossom (being a gentleman when she's about to fall and the whole bath scene); that lead to some things
-first, he prior lolification sees his mom as a mom and she sees her son as a son, no more, no less (bunch of degenerates all of you).
-second mom still treat her son as a son post lolification causing a very important dissonance between her and the other girls at his same age (a plothole if you want to see as it, because you cannot been the same person if your brain is different)
-and last, said dissonase tell to the boy that, regardless his logical part insist that she's still his mother, a more instintual part sees her as an equal individual (AKA a person with no autority above him) from the other sex who also show genuine affection (both in it's intention and demostration) to him
