1. A seal and damper system, comprising: a blade assembly seal having a length and a width, the length being parallel to an axis of rotation, the blade assembly seal comprising a central portion defining a recess and a depression, the depression spanning the width of the blade assembly seal, the depression being convex towards the axis of rotation; anda damper comprising: a center body; andan arm extending from the center body parallel to the width, the arm being configured to engage the depression. 2. The seal and damper system of claim 1, wherein the damper further comprises a protrusion extending from the center body into the recess. 3. The seal and damper system of claim 2, wherein the center body and the min define an opening. 4. The seal and damper system of claim 3, wherein the opening is configured to interface with the blade assembly seal. 5. The seal and damper system of claim 2, wherein the center body comprises a planar surface with the protrusion extending from the planar surface and the arm breaking a plane defined by the planar surface. 6. The seal and damper system of claim 2, wherein the protrusion of the damper is configured to slide relative to the blade assembly seal with a range of sliding limited by the recess defined by the blade assembly seal. 7. The seal and damper system of claim 1, wherein the damper is configured to clip onto the blade assembly seal. 8. A blade assembly, comprising: a blade platform having an axis of rotation;a seal configured to press against the blade platform, the seal having a length and a width, the length being parallel to the axis of rotation of the blade platform, the seal comprising a central portion defining at least two depressions spanning the width of the seal; anda damper clipped onto the seal in a direction parallel to the width of the seal. 9. The blade assembly of claim 8, wherein the seal further comprises: a first end extending away from the central portion and configured to contact a forward sidewall of the blade platform; anda second end extending away from the central portion and configured to contact an aft sidewall of the blade platform. 10. The blade assembly of claim 9, wherein a sidewall of the central portion defines a recess. 11. The blade assembly of claim 10, wherein the damper further comprises a first protrusion configured to contact the sidewall of the central portion defining the recess. 12. The blade assembly of claim 11, wherein the damper further comprises a second protrusion with the seal between the first protrusion and the second protrusion. 13. The blade assembly of claim 12, wherein a width of the seal between the first protrusion and the second protrusion is less than a distance between the first protrusion and the second protrusion. 14. The blade assembly of claim 8, wherein the damper further includes a first arm configured to slideably engage the depression. 15. The blade assembly of claim 14, wherein the damper further includes a center body with the seal between the center body and the first arm. 16. The blade assembly of claim 15, wherein the damper further comprises a second arm extending from the center body opposite the first arm. 17. A damper for a seal, the seal having a length and a width, the damper comprising: a center body comprising a planar surface;at least one protrusion extending from the planar surface and perpendicular to the planar surface; andat least one arm extending from the center body with a portion thereof extending substantially parallel to the width of the seal, the at least one arm configured to engage a depression on the seal, the depression being convex to the planar surface. 18. The damper of claim 17, wherein the at least one arm includes a first arm and a second arm that break a plane of the planar surface. 19. The damper of claim 17, wherein the at least one protrusion includes a first protrusion and a second protrusion that extend a substantially equal distance from the planar surface.
