Both Claire and Marie, in their tank tops, seem to be wearing the most appropriate clothing so that, as they bend over Sophia (or possibly Dylan) to cut her (his) hair, they can show her (him) their breasts (maybe even a nipple). If then, while shampooing, some water were to inadvertently splash on them, maybe we could have wet T-shirts as well, but since L&P has unexpectedly begun to spice up each of his updates lately, I wouldn't be too surprised if something even more teasing happens that (fortunately) I can't really imagine at the moment.
Just one thing doesn't make sense to me and that concerns Dylan's presence: did he go to Chez Lucille just to accompany his mother or also to change his hairstyle again? But what male teenager changes his hairstyle every two weeks? Maybe he's there just to continue the conversation he started with Marie a few days ago during yoga class. Or maybe this time, instead of spending time playing with his phone while waiting for Mrs. Fleury to finish cutting his mother's hair (as happened in Day 2), someone could give him a broom in his hand to clean the beauty salon floor. For Dylan, it might even be a good opportunity to find (as we have already seen for Zac at the tanning salon on Day 17) a little job that gets him out of the house and maybe into Marie's arms. It could be one of the last opportunities (for those who are not interested in a relationship between Sophia and her son) to mate Dylan with one of the many female characters around him (first Emma, then Christine now Marie) and still continue to have interesting scenes to watch involving his character. Whether or not these "secondary" relationships of Dylan's, in the developer's plan, are compatible with Sophia's "main" path I cannot say, but, in case they are not, they might represent the last calls before the incest-city flight finally takes off.
PS:
Who knows if the "new" Dylan, once seated in the hairdresser's chair, will be able to touch the ground with his feet this time?
