It's hard to See here. More than cellphone service and the sheer effort of seeing anything when no one is around, there's something proprietary and Lonely about the land itself that's kept him to himself. Peter is only a few feet to his right, but Elias doesn't get the rush of Vision until after he's full ensconced himself in jacket, coat, and blanket, pulled another fold of fabric over his lap. 

Even when he finds it, it's clouded. Elias can see just clearly to note that the hostile edge he projects onto Peter is...noticeably absent. That there's real bittersweet, real truth in what he says: he came to take Elias away. 

The relief that pours off him is poisoned with guilt (for blaming him), muddied with bitterness (why didn't he know, why didn't he come sooner). Elias' shoulders slump under his coverings. "...I don't--I haven't been able to move well for a while now. I don't suppose you would put the kettle on."
