Parasagun's zyudenchi even gets tucked away, a full - and again, deliberate - demonstration of Ian's trust in the situation. And if that wasn't enough, he even strides forward confidently to throw a friendly arm around Souji's shoulders. You've been missed, boy.]
We'll have to let King, Torin, and the others know right away.
