Alena and the others are currently looking at Sam's direction seriously. At the same time, they are also worried about him. A huge spiritual fluctuation also appears in that place making them more worried about him.
Well, everybody already predicted that some kind of Mind protection is present inside of those people so definitely Sam will try to fight back and try to open that mind barrier. This is the reason that they are worried about him as they don't know if he would be able to unlock that barrier.
For almost 30 minutes that fluctuation was present in that place but after that It began to disappear and 10 minutes later it completely disappeared from that place. Only then do they notice that Sam begins to open his eyes.
But none of them disturb him. They just look in his direction with curiosity as they want to know if he is successful or not. At this time Sam also notices them and smiles at them.
