Turning his head aside, Davis saw his mother still cry over the fact that she couldn't reunite with her father. He more or less felt guilty because of it since he was the one who had told her to not reunite.
Reuniting was definitely a valid option, but then he won't be able to control the pace, thrown into dangerous situations instead. This was not his cautiousness but he believed that there was a huge possibility to occur. He felt like he could see it happening, more like a premonition even though he really didn't.
However...
For his mother, he felt that he should try to save his little half-aunt too, otherwise, he felt that there would be more sadness and depression within the family which he was against.
'Well, I at least have more than five years of time to make a move. Before that, I must learn how to change a person's predestined fate to extend their lifespan...'
Davis mused in all seriousness.
