Liam appeared to have the upper hand, but the punches Van did manage to land were enough to warn Liam that he would be feeling this later. Bruises would come and go, as would the pain, but it didn't mean it didn't hurt in the moment. He was going for nother punch when he felt an intruder between the not so tête-à-tête between him and Van jump in and bite his hand.
Perhaps Sasha didn't realize how much danger he was in at that moment. Even if injured, Liam was running on adrenaline and fury. A dangerous combination for anyone attempting to intervene ona fight long coming. He literally growled, sounding more wolf than human and then turned to Sasha. Without any hesitation, he grabbed Sasha by the throat, squeezing his thumb hard into the boy's larynx at full strength.
"Stay out of our business, loser," he said and spat in Sasha's face.
