At least he has the only working cell phone left in the universe. Will have to re-watch again next week to see what he actually said...all I got was "Ill be there".
One of two - he was talking to someone else. I'm assuming it's a satellite phone in hopes that they'd still be functional based on being in space, rather than cell towers that were nuked. I think it's a stretch, but I'll somewhat allow for it.
Family coping fine, our heroes show up, two of them die (at least). Yippee! Another reason to hate our merry band. These people are dumb. I really wish Strand would toss them all off the boat. Still operating like it's a democracy for the bleeding hearts. Blech.
