Finnabair

Am I the only one who thinks it is weird that Finnabair dies twice in The Tain? The first time is when Ailill and Medb offer her to Cu Chulainn and he kills her and the fool that she is with (Finnabairs Stone) then she magically shows up alive later on when Medb tries to convince Fer Diad to fight Cu Chulainn. Finnabair would be given to Fer Diad if he goes and beats Cu Chulainn, seeing as which Fer Diad dies Finnabair does not marry him and fades into the background, that is until Rochad Mac Faithemain comes around. Evidently, Finnabair had been in love with Rochad and they lay together well because Medb had used Finnabair as a tool one to many times the upset men went to attack Ailill and Medb which led to seven hundred men dying. When Finnabair heard about this she was so filled with shame that she dropped dead (Finnabair Sleibe, Finnabair of the Mountain). Does anyone else find it interesting that Finnabair is the only person in The Tain that has managed to die twice on two separate occasions?
