Were Simon psychically capable, or were he and Galadan closer acquaintances than they are --

Perhaps then Galadan would share the sentiment that, given his two remaining friends (besides River) currently reside in the Tam's home universe, there is very little he will not do to make sure a pathway of travel is available between there and here.

Whatsoever he has to do to manage it.

But as they are not close acquaintances and Simon is not psychic --

Galadan merely sits in silence, drinking another handful of water from the stream and keeping his wintry grey eyes on their surroundings.

Someone needs to be on watch, here of all places.
