Ben | Five
It was a different kind of isolation Ben had obviously experienced. And to have to be somewhat attached to Klaus, of all people, who had obviously done everything in his ability to reject and push away his ability for the majority of this adult life... that likely made a difficult experience worse. Seeing people, seeing Klaus, and being unable to interact with with the previous group at all times and the latter precariously.
"While our circumstances were different," he began, understanding at least a little, based on how his brother described it. "It took me a while to re-acclimate to other people." A beat. "If I can manage, you'll do just fine." Ben was immensely more social, it being a natural inclination of his. Five hadn't tried all that hard to be honest, hadn't particularly cared - he cared up to the point where it allowed him to better achieve his singular goal of getting back. Mission successful.
"As for decision-making, I can't help you there." That seemed a completely bizarre notion to Five, foreign and alien in every way. "Best advice I can give is to have a clear mind about what you want. And less over-thinking, more doing." Sitting and fretting about a thing didn't do anything a lick of good. Just act. Do. A problem their other siblings all seemed to have when the pressure was on.
Minus Diego. He did plenty, just none of it relevant.
