Still. There are days when Shoichi thinks he might be going down the wrong path.
Not for Yusaku- god knows the boy wants to achieve this goal as much as Shoichi himself. Sometimes he wonders about that, but Yusaku is always certain of his own path.
The boy says so himself- he understands the risks and he made his decision. Just because Yusaku doesn't know the whole truth doesn't mean he's not capable of making decisions.
No, what worries Shoichi is the separation from his brother. Their positions keep them apart, what with Rev running the entire operation in place of the founder and Shoichi assigned to Yusaku, and he can't help worrying about Rev. What's he doing? Is he taking care of himself? Is Specter giving him enough time to mature?
He knows that this was the best option when he took it- the only option that let him keep in contact with his brother. Nobody with half a brain would let Shoichi be Rev's watcher.
If push came to shove and Rev proved too dangerous, Shoichi would never be able to put him down.
More importantly, Shoichi knows that Rev isn't dangerous like that- that he'd never lose control. And because of that, Shoichi knows he'd be blind to any warning signs if Rev was about to snap.
Better to handle Yusaku. Better for Yusaku, at least. Most people think he's painfully stoic, but Shoichi's learned to recognize all of the little flags that prove he isn't. He knows that Yusaku doesn't always smile when he's happy, but sometimes he'll fidget instead. He knows Yusaku's methods of self-expression better than Yusaku himself.
Knows Yusaku better than Yusaku knows himself. Proud, pragmatic, driven Yusaku with too many thoughts and not enough friends.
The kid's tougher than he looks, but not as strong as he thinks. Shoichi can work with that- he's the only one who knows how to work with that. He makes suggestions instead of orders, points out flaws instead of prohibits, asks questions when nobody else would.
It's fulfilling to be his handler- his caretaker. It's just…
Sometimes Shoichi wonders if Specter does the same thing for Rev that Shoichi does for Yusaku. Sometimes he worries that his brother is being guided and directed without being loved.
