Great episode. I will admit the beginning with Syr & Bell in the bedroom did annoy me in many aspects. Although the eyes that Syr uses reminds me of what Freya used in S2, which she used to infatuate the guys with the Ishtar family. So that was a clear sign that Syr is Freya.
I also loved the talk Welf get Bell. He likes Bell as a straight shooter aka someone who is open. A guy who doesn't give a girl an answer right after he confesses is not taking that girls' feelings seriously. This is a talk that Bell needed especially right now. Bell has had his harem for a while, but nobody has been aggressive like this pursuing him.
The Horn twist when Bell realizes was executed very well. Since Hestia, herself didn't know what Syr was. It was currently that this Syr was Horn, not Freya. Essentially, the game between Horn vs Freya it was really about would Freya win his heart first or would Horn kill Bell. It is safe to assume that the Syr that was with Bell for most of the time on the date was Freya. Now I am not sure how they ended up switching.
Essentially, Syr wanted to be as beautiful as Freya. To become that, she forsakes her name and Freya made her the daughter of the Gods. One could think of it as her adoptive daughter. Freya fell for Bell all of this time. I wonder if this is the first time Horn was disguised as Syr or previous interactions. I do get the sense for the majority of them it has to be Freya.
The one big line that Syr mentions is that she wanted a slow burn romance. More and more Freya wanted to a slow burn romance. After all, as the Goddess Freya, she could take Bell by force whenever she wanted. However, she wanted to have a more pure romance it seems. Though after being rejected by Bell as Syr she realizes being the pure hearted maiden would never win him over. So there was no reason for Syr to exist anymore.
Despite how Horn says it to Bell that he knows everything. In reality, he doesn't. He knows at that time Horn was disguised as Syr. But he has no idea that the Syr who confessed his love to him was Freya. The even sadder part is that rejecting Syr's love essentially leads to Syr no longer existing. For Freya Syr was an avenue to express her love in a very human way. That rejection means for now her only love will come as a goddess. It feels like shyt is just starting to get down.
