new kind of behaviour?

i just had a game and i went 1/8 i think as tris, yeah reeally nice game... anyway all of the game i tried to tell rengar to stop flaming and start helping (i didn't flame a bit and you can check that). now let's put aside the flaming and the "no, you deserve flaming" part, what i wanna talk about is this thing that i've never seen happen before: rengo started a surr vote i said yes, the other three said no, no big deal. rengar: who said no? tf: probably tris rengar: yeah she carry

at that point i mentioned to them i'm the only one who voted yes therefore tf is lying and he voted 'no' but got no response, only more rengo flames later that game. i'm not here to speak about the normal flame and stuff. only to speak about tf lying. why did he lie?

oh and btw tf was not a friend of rengo so i dont think he did it to "get close to him or something" i really don't know...
