This was a bit of a gimmick to talk about the height of our hero.
It is assumed that Fenris is a little taller than a common elf, but no taller than a normal man, therefore, estimating that the average man is tall about 180 cm (5 cm + 5 cm less) I would say that Fenris is high around 1 meter and 70 cm.
And Alex is the same height, that to be a human being, he is not too low, but it sure is not high at all.
At first, this episode saw Alex tried to wield the sword of Fenris with one hand as does the elf, and he tipped right over on his back without mercy because he can not do this ... but then I said to myself, that if Isabela was there to hear the dialogue, she would have certainly some dirty thought.
And since I'm actually worse than her, the result was immediate ... and here we are.
