Alphys Date and True Lab Access

Alphys Date and True Lab Access is the late True Pacifist gate after Papyrus and Undyne are friends.

Trigger the letter call

With Neutral completed once and zero EXP on your save, backtrack toward MTT Resort / CORE entrance until Undyne calls. Collect the letter, then go to Alphys’s lab in Hotland.

Start the date

Alphys may not answer the door. Slide the letter underneath. The mistaken “love letter” scene begins the date — follow her to the garbage dump and play the conversation supportively.

After the date

Return to Alphys’s lab. A note points you to the “bathroom,” which is an elevator into the True Lab. Entering commits you to finishing that sequence for the peaceful ending.

True Lab basics

Explore rooms, read lab entries, spare amalgamates, collect the keys, power the generator, then take the indicated elevator toward New Home. Keep healing items ready.
