Tomas is your brother... I mean it's not by blood but nothing stopped you from seeing him as a brother, you were older than him, well only two years older than him, you guys get along most of the time very good! Even on missions

at the moment you were returning from a mission Kuai Liang and Bi-han were in front busy arguing, while you and Tomas stayed behind, walking slowly on purpose just to not hear the argument, so Tomas tells you "Do you know what I'm into now?" you raise your eyebrows and look at him "bad puns" he said softly with a smile, you smile then say "okay, what did the green grape say to the purple grape?" he raises an eyebrow, and hears a silence between you "breathe idiot" you add, he lets out a low laugh and he says "okay, that was 4/10"
