Heres the phase 1 intro script:

*Fades into sans with closed eyes*

"So we're finally here,"

"Standing alone in a doomed world."

"With your goal being to kill me, and all humans beyond this mountain..."

*Eyes get the black effect*

"But who ever said I'd let you finish me?"

"NO ONE."

*Black Screen Shows for 0.5 seconds then disappears to show sans face up close with his bad time eye shown in gif*

"I WILL MAKE SURE YOU DIE A PAINFULL DEATH"

*screen quickly fades white and back to normal brightness. Phase 1 begins.*
