Asgore = He's already in the line (Even before Toriel knocks him away)

Toriel = Walks upwards to get in the line (To interfere Undyne and Alphys' romantic action)

Undyne = Walks upwards to get in the line (To talk to Asgore)

Alphys = Walks upwards to get in the line (To get close to Undyne before moving to the right)

Papyrus = Walks upwards to get in the line (After hearing a bad joke)

Sans = Walks downwards to the bottom edge of the screen, appears from the top edge of the screen and walks down to the gap between Toriel and Alphys.

So the point is, Sans used a 'shortcut' to get in the line with other monsters. Notice that he's the only one who walks downwards to get in the line.

I'm pretty sure someone will reply "I think he's going around the screen for that". I know, but it must have taken longer to get around the screen, he's definetely teleporting.

It should be added to the trivia section describing his ability to teleport.
