After hearing from Maester Thad that he prepared a message to Jon Arryn in the name of Ser Carsen, Teddy wrote the following message himself:

Lord Arryn,

I write to reassure you that House Jasper, as Warden of the Fingers and Isles, holds a strong presence and respect amongst the houses of the region, and you can rest assured that minor issues between such parties will be resolved swiftly and equitably. Your Lordship need not mind any petty grievances from disgruntled House Lords, for we are seeing they are brought to a close without requiring your intervention.

Yours,
Theodore Jasper
