Tobias's older brother has to clean up his mess and even admits, as a businessman, if he wasn't married, he'd gladly take Dahlia and give her the respect she deserves (without any feelings he admits but at the same time, he also admits that he respects her so much just for her creativity and it was incredibly stupid of Tobias and their mother NOT to realize what their father was planning with the engaement since both Tobias and Dahlia surprisingly are able to compensate what the other lacks: Dahlia in her social skills and even in her creations, Tobias was meant to be her safety break (if she ever becomes so grossly involved with her research that it either jeopardizes her health or is researching something dangerous, Tobias was supposed to be the safety net and remind her this is something the general public needs to use (and should be affordable and safe to use)
