The others were in such disbelief when they saw the person in front of them that they thought they were dreaming. Quinn had gone missing for a while now, long enough that they assumed it might be years for him to return.
Or, if they really wanted to find Quinn, then they would have to find him himself. The only thing was, they had no idea how determined Quinn was to get back to Earth and return to the others to see if they were okay.
When Quinn saw the large ship, he had no clue what it was or who it belonged to, but he could sense that Peter was using his celestial energy now. The amount used was increased, and without a doubt, he was fighting.
Because of this, he didn't slow down as he busted through the many levels of the ship, following the energy like a red arrow. Quinn used his red aura to easily bash through the levels one by one until he eventually landed in front of the others.
