The assembly as recited in claim 9, wherein the damper biases the seal carrier. 11. A stator assembly for a gas turbine engine, comprising: at least one stator vane including a platform;a seal member connected to the platform; anda damper between the platform and the seal member, the damper including a plurality of first fingers and a plurality of second fingers, the damper further including a first piece supporting the first fingers and a second piece supporting the second fingers, wherein the first and second pieces are initially formed as separate structures. 12. The assembly as recited in claim 11, wherein the damper includes a bridge piece connected to both the first piece and the second piece. 13. The assembly as recited in claim 12, wherein the bridge piece is in direct contact with the platform, and wherein the plurality of first and second fingers are in direct contact with the seal member. 14. A damper for a stator assembly, comprising: a plurality of first fingers;a plurality of second fingers, the first and second fingers provided in an alternating arrangement;a first piece supporting the first fingers;a second piece supporting the second fingers; anda bridge piece connected to both the first piece and the second piece. 15. The damper as recited in claim 14, wherein: the first piece includes a first finger support;the second piece includes a second finger support; andthe bridge piece is connected to the first finger support and the second finger support. 16. The damper as recited in claim 15, wherein: the first fingers extend from the first finger support at a non-zero angle; andthe second fingers extend from the second finger support at the non-zero angle. 17. The damper as recited in claim 16, wherein the non-zero angle is within a range of about 10 to 30 degrees. 18. The damper as recited in claim 16, wherein the first finger support and the second finger support extend in a direction substantially parallel to one another.
