The first, second, and fourth Echoes are approved - provided, in the case of the first, that he holds/handles one of the guns himself!

To clarify on the third, however, might a particular thing happen between Gavin and the kids that'd "remind" him of Gale's old group - or will it mostly be Gavin's attitude toward/role in relation to them that'd parallel Gale's to Tribe Embryon?
