It isn't until she embraced him that he realizes that she's indeed real.

Benjen's confusion turned into relief and his surprise into happiness. Tears dampened his cold cheeks as he hugged his sister as tightly as he could. The warmth that radiated from her warmed his heart literally and figuratively. He's longed to see Lyanna again but only could see her in his dreams. "It's really you." He whispers as he reluctantly pulls back. Benjen stares down at her with a look of sheer joy upon his weathered face. Lyanna looks exactly as he remembered her. Young and full of wild eagerness. It's almost as if she hadn't aged a day since her death and was left immortal and flawless.

"The magic...?" Benjen pauses for a moment as he glances along the pier briefly. This place is indeed magical but it seems oddly mundane to him. "They're here too?" He can't help but be elated to hear that. As he laid there dying on the snow, Benjen longed to see his family again. He missed the little ones and missed his brother most.

"Ha, you humor me! I know I'm old." He says with a grin.
