Maybe to regular family members, asking one's siblings for a favor wasn't a big deal.
In fact, Rayna had even seen it occur among the regular citizens during the first attack on Flendon.
Those willing to take up arms for their family, brothers willingly sacrificing their lives for their little or even big sisters.
However, for Rayna, it was different. The Neverfall Clan, sticking true to the Demonic Clan ways, didn't care for blood ties—everything was about power.
Han and Fing were both second to Belil in terms of power. So Rayna asking them for a favor was like asking a boss in a large company to do something on their behalf.
It was an awkward feeling for Rayna, and in the world of warriors, where she was related by blood, asking was an embarrassment for her.
Yet, she was willing to swallow her pride in this moment to ask for this favor.
