Pleione is a prototype of a group of Be/shell stars that represent cyclic changes in their spectral appearance. The star was suspected to be a binary or multiple system. In the present study we are trying to obtain more precise picture of going on spectral changes of Pleione by data-mining in existing archives of Be stars spectral observations. New results reveal unknown before details about developments in the circumstellar envelope of Pleione, connected with the interactions in the system.
