Natasha looked up at the touch and smiled. She'd heard him coming and knew from the footsteps who it'd be, but had taken just a moment longer with her own thoughts - but she didn't mind the interruption one bit.
"It's good to see you, as well," she replied as she moved to her feet so she could face him directly. Before either could say something further, Natasha stepped in and gave him a quick hug. Despite the fact that she was well-used to people coming back to life here, to see that she was right and Thor was in one piece was something of a relief. Normally, she wasn't often the type to go for a lot of physical affection, but she could make an exception in this particular case.
When she released him and stepped back, Natasha gave a nod. "It's my pleasure," she replied, before reaching down past the chair to pick it up carefully and hold it out to him once again. "You need to learn how to hold onto your weapons better," Nat teased lightly before giving him a slight grin.
