I always thought that the the most courageous act Claire had the strength to achieve was to get back through the stones to return to Jamie. Of course she loved him, but she wasn’t sure she would survive, she didn’t know exactly how it worked and yet she was ready to take the risk because she had made up her mind that she wouldn’t live without him. After all, she didn’t know what she was to find on the other side. Even if he was still alive, he could have changed, carried on with his life in a way that wouldn’t include her. And yet she decided to go. I always admired her for that. I hope that the next episodes and seasons will continue showing her as the strong person she is in the books (and a little more than they showed until now).
