He's waking up !

Lena after hearing this felt really helpless, the fact that she couldn't help Ian like she had helped Jordan really worried her and she asked them : "But isn't it too dangerous for Ian ?"

Caleb then said to reassure her : "Ian is healthy and he has his husband to look after him so don't worry about him. Get your strength back princess, because if your man when he wakes up is under the influence of the black particles, he will need you badly."

Lena nodded and finally, after only a few minutes of struggling to keep her eyes open, she finally fell asleep.

While Ian continued the extraction, Jordan rested and two hours later they switched roles again.

Ian had nothing to protect him from the negative effects of the black particles, so when Liam told him to stop, he did.
