Residue

Residue:

Residue is caused when a headmate leaves front or a layer/area of a system and leaves an echo in front or that area. The next headmate to front might find themselves prompted to type, speak, or act like the headmate that left or might be confused on things they like or dislike. Some headmates might be more prone to leaving residue than others.

Residue includes echos left by headmates not usually in an area whether due to being in a different layer or coming from another system. Any systemmate including soulbonds and travelers can leave residue.

Bleedover and passive influence describe similar sharing of feelings or mannerisms, though they usually refer to interactions rather than something being "left behind".

Switchlag may be caused by residue.

Whiplash is the intense feeling of negative emotion, or dissociation, that comes over a headmate when entering front.
