After what looked like a no-win scenario had unfolded for Askeladd, Thorfinn, and Prince Canute, the standoff actually de-escalates when Askeladd starts speaking Welsh, to the surprise of even Bjorn.
It’s his assessment that their “hosts” from Brycheiniog won’t do them any harm, but they cannot let a horde of Danes cross their lands unchallenged, hence their intimidating posture. Askeladd tries to get Canute to intimidate them back, but the prince hides behind Ragnar.
Askeladd and Gratianus have a private meeting with the Brycheiniog commander, Asser, in which Askeladd reveals that he is half Dane and half Welsh, and a living descendant of the legendary King Artorius of Brittania, who inspired the legend of King Arthur.
The episode’s cryptic cold open depicts him in his youth bringing his dying mother back to Wales, and Gratianus greeting him. It should be noted young Askeladd looks a lot like Thorfinn. No wonder he’s taken such a shine to him; he’s the son he never had.
Anyway, Askeladd agrees to hand over the weapons of all his men and allow themselves to be escorted across Brycheiniog so Asser and his king can save face and look good to the common subjects. In exchange, Askeladd will see to it Canute is the one who succeeds the Danish throne, which means he’ll have a powerful seat at the table with which to ensure a treaty of non-aggression with Wales is arranged.
The fact of the matter is, Askeladd hates the Danes, likely in part (if not mostly) because of what they did to his mother. He seems as intent of keeping Wales unspoiled for her sake as anything else. But between some concerned looks from Bjorn and some groaning of his men, he will be testing their loyalty—and the secrets he’s kept from them—to their furthest limits by changing their route to Gainsborough.
In the meantime, Prince Canute finally hits his limit for enduring verbal abuse and mockery from Thorfinn, and calmly explains that as a prince he must be more cautious with his words…before abandoning that cautiousness to give Thorfinn a piece of his mind. Ragnar is shocked, but in a good way; he knows more than most how he might be hurting the fledgling by not insisting he leave the nest.
Still, Ragnar’s desire to protect a child who has already endured so much (Canute’s childhood was not a happy or peaceful one) seems to override that logic. It’s probably heartening to no end to hear Canute speaking to someone other than him; it means Canute and Thorfinn are, against all odds, developing a rapport. That can only be good for the both of them.
