I think No Time Left may go like this
Into The Fire - Lee and the rest try to escape the horde of walkers
Twice Shy - Omid ( possibly ) is seen getting bitten after his leg screws up while the group are escaping as the group take refuge somewhere.
There Ain't No Way - Christa, Kenny, Lee, Ben ( Determinant ) go looking for Omid's remains. They see walkers feasting on Omid's body, then Christa, failing to cope with Omid's death, commits suicide, while Ken, Lee and Ben ( Determinant ) try to stop her. The sound attracts walkers ( Many of them ), and prompts Kenny to say “There ain’t No way”
Mercy – Lee gets grabbed by walker, reanimated Omid maybe? Then Kenny’s got his back and saves him. ( not sure what to say for this )
The Marsh House – The group take refuge at the Marsh House. Lee fights Campman and blahblahblah possibly kills him and saves Clem. Clem’s parents ( undead or alive ) are probably in there.
Whats in the bag – The group’s remaining survivors, Lee, Ken , Clem and Ben, look outside towards the gigantic horde of walkers. Seeming impossible to escape. They look for weapons as someone finds a bag with explosives in it.
Stay Close to me – Lee offers to detonate the bomb as he may not have much time left. Lee spends his last moments with Clem and tells her to stay close to him as the group head out into the horde. Lee charges with the bomb into the horde and BOOM. Many walkers die + Lee. Ken, Clem and Ben ( possibly Clem’s parents ) run towards the boat and make their escape. The boat can fit 5 people so it should be Ken, Clem, Ben, Ed and Diana.
What remains – what remains of Savannah. Someone is standing on the crater that the bomb detonated on. That someone is probably season 2’s character. Or Campman.
