it's sooooooo carlos and TK to see them so attentive to each other even when now they're not alone anymore. they're a unit of three but carlos is checking on him about having no regrets, then again about going back to the firehouse without his dad and TK doesn't catch that at first, but carlos really knows him to the core, he knows TK's'it's the first time going through it without my mum' he knows how much it feels like TK's first day of school when you parents have to leave you at the door and you're on your own before you settle in. he doesn't know this firehouse without his dad and it's such a big moment after a big shift for him and for owen but carlos is right there by his side being the capable loving man that made owen feel safe and sure that his mission is done here. and there is TK being his alarm, waking him up so doesn't miss breakfast or rush to his shift, thanking him for taking the time because time with loved ones is TK's idea of love and carlos will speak his love language right back at him without asking. it's such a small glimpse into this new life but it's so good seeing them still, always and forever being the axis of each other's lives. they're taking care of each other emotionally and in every way else and that's tarlos for you!!!!!!! having more weight on their shoulders or responsibilities or becoming a family only makes them want to fight harder and love deeper
