Ever since Oliver revealed the obvious fact that it was possible to find wild vegetables and different types of food in the Gates, the atmosphere in Dilan's group had changed a lot.
While many had been frustrated about having consumed nothing but monster meat for weeks, they were much happier when Oliver and the others returned with some fruits and wild vegetables.
Dilan had not expected them to find results so quickly but he was not actually surprised.
The fact that the Ascenders were able to get their hands on something they wanted to clearly showed that their strength was higher than they assumed.
This was enough to boost their self-esteem once again after it had been crushed in their last mission in the Pagoda of Time.
Dilan's mood had gotten much better than before as well, and it looked like everyone was slowly getting back to their senses.
