The scene he saw flashed back towards them having sex at the backyard garden where his mother tenderly and with labor grew the beautiful flowers in the garden. Ever since she married Vlad she had completely stopped working and coupled with her poor health she focused on being a housewife. Thus when she had nothing better to do she tended the garden while still pregnant with Uoron.
The coincidence of their age, the timing the year his mother had given birth to him, Maya also took a long break from work wherein Vlad coincidentally had an inspection outside the country for a few months which was why he was not their when his mother gave birth to him as shared by his grandfather.
Even a stupid person would realize that these were by no means a series of coincidence. He laugh and laugh while tears fell from his eyes that night after going home form the so called family meeting between them four. Ever since then he had changed from his warm hearted and childish behavior into this cold and aloof persona.
He and Claire had a great relationship because he never blamed her for the wrongdoings of their parents. In fact Claire prior to being sent back was also oblivious who her mother and even who her father was.
Claire was highly afraid of this couple especially knowing how they treated her beloved brother.
As soon as she could remember she had lived abroad with her Nana and was only asked to return when her nana told her everything on her deathbed as she died with old age.
Coincidentally the couple's obstacle being Uoron's grandfather had finally died, this enabled them to openly acknowledge their relationship though they only said they became a couple just recently.
Uoron felt slightly guilty towards Claire as even though he they were both neglected they lived two different lives, him having a more luxurious and more comfortable life as compared to his step sister.
Though Claire lived a comfortable life but as a foreigner living a life outside of her country discrimination and bullying is a usual occurrence so he was highly pampering towards this cute and silly little sister of his [1].
Claire on the other hand never felt she was deprived and didn't really mind the bullying and discrimination as she actually got used to it, as she grew up these things lessened.
But did not stop her from wanting to be pampered and spoiled, in return for his love for her she actually took it upon herself to hinder the bad ulterior motivated woman and clinging woman surrounding her handsome brother [2].
Vlad knew that if he had married Maya while Arthur was still alive he would defiantly disown him as even if his daughter died a few years ago, he believes that he should still be loyal to her which he thought was absurd but as he didn't what to lose his inheritance he and Maya decided to endure.
But what he did not expect was despite how they tried to hide their relationship [3] the old fart would still found out [4] about it, leaving 95% of the company to Uoron. The good thing was he could still manipulate Uoron but sadly because of his rash and hasty behavior his control over him shattered.
[1] Sister complex!!!
[2] Brother complex!!!
[3] He did not know that they had discovered them during the "deed"
[4] He repeatedly underestimated Arthur's skills even sometimes forgetting he held the second strongest power in the underground industry.
