Arthur had decided to confront the man he saw several times with his woman, "Hello... Robert." He greeted starting him as he hadn't known that anyone was closely behind him.
"Yes, how may I help you?" He asked, "yes, you may. I'm Winifred's soon to be husband." Arthur introduced cockily simply waiting for the man to make a little mistake so he could have an excuse to punch him in the guts for even daring to touch Winifred.
"Oh... the one who broke her heart and replied her letter to him with such demeaning and heartbroken words? That's you?" Robert accused immediately, although he also felt threatened by his presence and was hoping that he remained whatever stance he had written in that letter because otherwise, it would mean that he had no chance with Winifred anymore and he felt like they were getting somewhere already.
