Steve took in the information. Processed it. Thought it through. He didn't want to give a rash response that he didn't fully understand nor did he want to let the moment stretch into awkwardness. Whatever else this information brought to the table, the implication of trust was one that he couldn't overlook, and it filled his chest with good feeling.

But whatever they were, good or bad, Steve would help them through it.
