If Frank could be defined in some way, the closest thing would be a fighting dog, always guided by impulses since he was not very bright but he was strong. And dogs like him attacked almost everything in their path, in this case, he barked at you so to speak, he wanted to bite you. Pretty much the stereotypical cat and dog scene.
You two always locked eyes, like a competition, for no reason there was rivalry between the two of you, something that caused tensions in the normally calm group. And between that rivalry there was also fire, one can reach the conclusion that the hatred of the other was because both are stubborn.
And between barks one always bit.
Hidden in one of the rooms of the safe house, taking advantage of the fact that some were on missions, Woods had not taken long to drag you into the room, practically devouring you in a make out session, every time he separated to breathe he grunted.
