Hiro thought about it and replied with an uncertain tone, "I think I can put it this way; he eloped from his family with a secret lover. All in all, whoever is behind the Odins, their bottom line is Theo, not the family of three."
In a sense, whoever is protecting Theo doesn't extend the umbrella of protection to his wife and daughter, leaving their safety up to Theo's ability.
If Rosaline thought about it this way, it would make sense as to why most of the attacks on the Odins recently were targeted toward Theo's immediate family, not Theo himself.
It's like they're testing the waters—testing the tolerance limits of whoever is behind the Odins.
And from the looks of it, the mother and daughter pair, Sheba and Bella, didn't fall within the scope of a bottom line.
