Veronica didn't even hesitate to wrap her arms around him as soon as he took her hand. Yes, he felt more compact, thinner...but she hadn't registered much beyond his longer hair in his change of appearance, mostly because she had more important things to think about. She felt so...young and useless. He needed someone who was wise and who had lived the same kind of life to help him, really, but she had a bit of a selfish savior complex in her and no matter what, she was going to stick with Sam and help him however she could. That was Veronica's way. She didn't give up very easily.
"You're handling this as best you can," she said into his chest, her breath heavy, but no tears coming. They had gotten through worse. He still loved her, he still had his soul, so everything was easy compared to that. These things were just hiccups in the grand scheme of things. Hadn't they weathered so much already? They could do this too.
She turned her face up to his, and at once it hit her how hollowed out and older than his years he looked. "Oh Sam," she said softly, reaching a hand up to lightly caress his face. "So much living in so short a time...I'm so useless to help you, but I'm going to do it anyway. That's what a Mars DOES."
