The gesture was so simple, so sweet. How could Thor not return that small love Diana was giving to him? Their hands laced together like that and he let her lean on him, being strong for her when she seemed so drained, so small compared to her normal self. It was daunting, seeing her let herself be so vulnerable with him, but then again, it wasn't the first time.
"We can take it together." He assured her. "Any challenge, anything this place might throw at us. You and I are the strongest of our kinds, apart. But together? The strongest of anything. We're unstoppable."
He wanted to remind her that even death couldn't stop him, but that seemed a step too far. Instead, he gave her hand a reassuring squeeze and fell quiet, letting her just have the moment however she wanted.
