Now here some things I notice and write here after replay the 1st episode when Lee walk around in the house:
- Lee took a walkie-talkie out of a cabinet in the kitchen, so the parents don't have the other walkie-talkie.
- On the fridge there is a piece of paper and he said: "Hmmm... The Marsh House. That's a Savannah area-code. But that's the type of note you'd leave a babysitter."
- Diana the mother told the babysitter Sandra: "We're still in Savannah. Ed had a little "incident" with some crazy guy near the hotel, so we had to get him back to the ER and have it checked out. Anyway, he's not feeling well enough to drive back tonight, so we're staying an extra day. Thanks so much for looking after Clementine, and I promise we'll be back in time before your spring break!" The message was left at 5:43 P.M.
- 2nd message: "Oh my God, finally! I don't know if you've tried to reach us; all the calls are getting dropped. They're not letting us leave and aren't telling us anything about Atlanta. Please, please just leave the city and take Clementine with you back to Marietta. I've got to get back to the hospital. Please let me know that you're safe." Message was left at 11:19 P.M.
- 3rd message: "Clementine? Baby, if you can hear this, call the police. That's 9-1-1. We love you... we love you.... we love y-" Message was left at 6:51 A.M.... At the last message you can hear her mother must be outside and was crying at the end
So I'm assuming that the parents must be perhaps in the hotel where the group perhaps also is. Another fact I have to add is, that from Savannah to Marietta are over 400 miles. And 2 facts because the group is in Georgia the achievements in the next episode are called:
"Georgia's first city" and "Georgia's last city"
We can be for sure that the "crazy guy" Clementine's mom mention must be that guy from the walkie-talkie, so he kinda must had a walkie-talkie or he met Glenn "his friends" (Glenn named them at the end from episdoe 1) because he (Glenn) was on his way at the end from episode 1 to Atlanta.
EDIT: I did also some more research and the Kings way is a actual street in Savannah and it's at the end of the south... in the preview video where Lee ask where the stranger is he stay behind a church, so a church is also pretty close to the King's way. The Marsh House is near the water but in Savannah in the "real word" there is a hotel called the "Marshall House"... if the group want to reach the "Marsh House" they have to go all the way up to the north.
In episode 5 there is also a achievement called "Marsh House" and that's nearly the end, so we have to deal perhaps with the stranger to the 5th episode and I think we see Lilly back helping Lee & Clem and give them "Mercy" (a another Achievement) before she die.
