The principal scribe (M) was responsible for writing down the main text, while a later reviser (H) erased the ending to make room for his own sequel from the time of Cú Chulainn's birth.
Her pregnancy is a scandal as she is betrothed to Sualtam mac Róich, and the Ulstermen suspect Conchobar of being the father, so she aborts the child and goes to her husband's bed "virgin-whole".
[4] In the later, and better-known, version of Compert Con Culainn, Deichtine is Conchobar's sister, and disappears from Emain Macha, the Ulster capital.
As in the previous version, the Ulstermen go hunting a flock of magical birds, are overtaken by a snowstorm and seek shelter in a nearby house.
[5] The nobles of Ulster argue over which of them is to be his foster-father, until the wise Morann decides he should be fostered by several of them: Conchobar himself; Sencha mac Ailella, who will teach him judgement and eloquent speech; the wealthy Blaí Briugu, who will protect and provide for him; the noble warrior Fergus mac Róich, who will care for him and teach him to protect the weak; the poet Amergin, who will educate him, and his wife Findchóem, who will nurse him.
