Warning: TOD and ACOWAR spoilers.
Honestly, if you think about it, Feysand and Chaorene are really similar...
1. The 'die together' bargain with Feysand is kinda like Yrene's power tying her and Chaol together, y'know?? Like, if one of them dies, the other does too...
2. Feyre and Yrene are the only ones who actually get pregnant in the series XD
3. Urm... Feyre and Yrene both have brown hair??
This is the lamest chapter I've ever written, my most sincere apologises.
