Everyone basically knows the rule. Never get between two partners.

Soap just returned to base from a six week long mission and his body aches for his lover. He knows he has to be here somewhere, he practically sensed his lovers’s presence.

Finally he spots his beloved and immediately shoves through the crowd. A walkway is created. No one wants to come in between the lovers, after all.

So close, the mere proximity is enough to ease any discomfort from Soap's chest.
