We give a new characterization of Littlewood-Richardson-Stembridge tableaux for Schur P-functions by using the theory of q(n)-crystals. We also give alternate proofs of the Schur P-expansion of a skew Schur function due to Ardila and Serrano, and the Schur expansion of a Schur P-function due to Stembridge using the associated crystal structures.
