...What? When is this? Actually it happens twice in a way:

The big one is on a Souless run, where you see a different reflection in the pools beneath Frisk as he moves through the rainy part of Waterfall. That reflection looks very Chara-like.

The second one would be where the stripes on Frisk's shirt flash between one and two stripes when you go into Sans' room.
