^ Lol you are right on all fronts - tho I would say they are deffinatley US military ID tags - which makes sense as something Kay would wear.
And I forgot / didn't really think about the fact Dajeelings hair was braided up hence probably a bit long when not.
Also on hair colour, I thought I remembered Darjeelings being a bit reddish blonde and Kay's being blonder so I got them the wrong way round lol. I checked an ep and both are full on blonde - but Kays is slightly darker.
Wow, two requests of mine in one upload (this and the Gabriel Dropout one. Well, not that I was the only one...)
@Midnight, they don't exactly say they're a couple, but I can't get more much more canon anyway. https://youtu.be/_oCcNjeqQRQ Pretty crappy video (didn't find a better one), but it gets the point across. Basically a recap of (the famous) ep.11 (Obviously Spoiler).
Yeah it's a military tag dang I missed that. I agree with you in the movie too Kay and Darjeeling are shown to have almost similar hair color, Kay's a bit darker than Darjeeling but in different movie scenes it's hard to tell, not that these two have that much screentime to begin with. Acc. to wiki though Kay is strawberry blonde.
