The grove probably is the best choice for Gabriel, just because of how long he'd been in the grove around his own Temple in the forest. Because the grove and the forest itself had sustained him until Sam had come to him.

Sam takes a similar look around and nods, offering his hand to his brother. "I guess we'll see each other in a couple of hours." Because, yeah, Sam's not going to be moving from the grove until he's ready to let Gabriel go. And he knows from the few times that they've raised power this way that that's going to be a good while. Especially since, with any luck, there's going to be a lot of power raised tonight.

Once they part ways, Sam goes to pick up a small pack that he'd brought with him, sliding his arm around Gabriel's shoulders. "The grove okay with you, then?"
