Walt delivers the inventory in time to meet Gus' deadline, but no thanks to Jesse, and misses his daughter's birth because of the drop.
Jesse confronts Walt about his share of the payment, but Walt refuses to disburse the funds until Jesse can prove his sobriety.
Jesse and Jane's addiction is discovered by Jane's father, Donald, who gives her a day to square up her affairs before going to rehab.
Walt Jr. sets up a website to gather donations for his father's medical expenses. It is quickly used by Saul for other purposes.
After discovering Jesse's payday, Jane blackmails Walt into delivering Jesse's share. By chance, Walt meets Jane's dad at a bar.
Later, Walt returns to Jesse's to attempt to make amends, but finds Jesse and Jane passed out in bed after a drug binge.
He tries to shake Jesse conscious and as he does so, Jane flops over onto her back, vomits and begins to suffocate.
Walt does nothing to help and watches her die.
