Narrative:

Air carrier X deviated for WX into air carrier Y also at FL350. After working at the sector with other aircraft deviating a WX route took shape in my mind, but air carrier X pilot deviated way beyond that route, and my attention being dispersed, his track went unnoticed too long. Corrective action taken, turned both aircraft and descended one.
