Ah ok. I have the answer:Thyunda said:The baby in Cerys' arms was clearly crying, and she'd evidently snatched it in view of the jarl's guards to encourage pursuit. She hands it to Geralt, Geralt tosses it in the oven and casts Quen on the door so nobody can open it and fights off (brutally murders) the jarl's men. Jarl collapses in defeat, Cerys and the old guy reveal the baby Aki was safe all along. This is where it gets a bit weird - did Cerys carve a hole into the back of the oven so that they could pull Aki out before he was hurt, or was Aki in the old man's arms the whole time behind the wall? If so, who was the baby in Cerys' arms and why was it crying if it was fake? Did Geralt actually throw a peasant baby in the oven to fool the jarl and the hym into thinking it was his?
I tried it once without throwing the baby in there and Cerys then reveals that she found a secret back door to the oven when She and Geralt were both in the House and Geralt was one room over. Basically she got into the next room and pulled the baby out before it could be harmed by the warmth. That's why Cerys and the Priest came out of that direction to fool the hym.
