Sir Kay is the seneschal of Arthur's household, the foster-brother raised alongside the king and entrusted with the practical running of the court. His tongue is famously cutting, and he often tests newcomers with scorn before their worth is proven, a habit that makes him both comic and quietly important. Bulfinch uses him to show that not every knight earns glory by the sword; some hold the hall together while others ride out.
