Shouldn't it be gamma and γάμμα; https://en.wikipedia.org/wiki/Gamma https://el.wikipedia.org/wiki/%CE%93%CE%AC%CE%BC%CE%BC%CE%B1
It's not a coincidence.
The Latin and Greek alphabets are also related to each other.
Yeah! I love how many alphabets Wikipedia can teach you about. I just wish they could be a little more informative on Old Italic. (And that I had more escuses to use them in real life!)
Also, cool TARDIS. I think they should have Doctor Who skills as bonus lessons. I would enjoy that.
