ShieldShock Image Set/Imagine -
Steve and Darcy are each stoic in their own way.
Most people expect Steve to be the Captain every moment, to lead and always show strength.
Anyone who spends time with Darcy expects her to look after others, be funny, and speak bluntly.
Both of them only let others see what the others need to see. But everyone has feelings, even heroes and helpers.
Darcy and Steve recognize, understand, and respect their shared stoicism as they first become friends, but eventually much more.
