Friday's nightmare journey from South to North was forgotten and Argyle were comfortable winners.
Fallon scored the opening goal after good work from possible Aberdeen target Steve MacLean forced a corner that Fallon scored from and the 2nd goal came from the Don's other Argyle target Jim Paterson.
Romain Larrieu was back in goals and there was a strat for Bradley Wright-Phillips.
