Porque Ronan era indesejável para se alimentar, mas não impossível de se alimentar de
Em corredor :
DEX: I was captured during a culling on my planet. I was taken to a ship. A Wraith started to feed on me.
FLASHBACK. As the Wraith stands with its hand plunged into Dex's chest, its expression changes and it looks perturbed. It looks down to its hand.
DEX: Something made him stop.
FLASHBACK. Dex has been taken out of the cocooning and three Wraith are surrounding him. One plunges a syringe-like object into his shoulder. He is lain face-down on a table and a Wraith takes a knife and starts to cut into his back. Dex grimaces in agony.
Note que o Wraith está perturbado. Não está com dor nem nada - apenas aborrecido. Eu não tenho uma tela à mão, a expressão exata provavelmente seria útil. Aqui está uma captura de tela da cena, mas não tenho 100% de certeza de que essa seja a reação do Wraith a Ronan.
Também é bom notar que em Runner, o Wraith está tentando "comer" Dex durante um abate típico. Se Dex não "provar" bem, os Wraith têm muitas opções. Em Broken Ties , o Wraith está tentando torturar Dex especificamente em servidão:
WRAITH: Ronon Dex. I looked forward to the day when you would finally serve me.
DEX: Well, then, I'm gonna feel real bad disappointing you.
WRAITH: Oh, I'm sure you'll try, but in the end, you'll come around.
E está fazendo isso "alimentando" e "alimentando reversamente":
The Wraith still has its hand on Ronon's chest. Ronon looks old and grey and ravaged, but slowly his youth returns to him and his appearance goes back to normal. The Wraith pulls its hand away. Ronon gasps in exhaustion.
WRAITH: How does it feel to have your life stolen -- to be pushed so close to the darkness, only to be pulled back from the brink? From what I understand, it's a magnificent sensation.
DEX: To be honest, I've felt better.
Assim, alimentar-se de Dex pode ser desagradável, neste caso, é apenas um aborrecimento para o objetivo mais longo de fazer Dex seu escravo.
