UNDERTAKER KILLED AGNI! Fight me!! ヽ(`Д´)ﾉ (jk dont.. as to why I think that read my previous post)

This is my analization of the situation till now...
So there are two persons who entered the mansion and then killked agni, the first one which soma appears to be very friendly with and is shorter than him (soma looks down when he talks to him) is probably someone who looks a lot like ciel (im with the twin theory) I dont think its lizzy because he wouldnt act so friendly and probably be more formal to her,, if you look back on the chapter where agni sees the photo, it seems like he expects something to happen and runs to soma with a frightened face and realizes that what he feared for is happening and soma is being attacked,, as he gets worked up and tries to attack soma's attacker he pauses for a moment (maybe because the attacker looks like ciel) at this moment he gets stabbed by ciels lookalike's companion who says that he will deal with the rest and that confirms the two attackers CALL ME CRAZY BUT I THINK ITS UNDERTAKER WHO KILLED AGNI!!!
remember what undertaker said in chapter 105? http://www.mangago.me/read-manga/kuroshitsuji/an/manga/kuroshitsuji/v20/c105/pg-25/ "the earl of phantomhive is still with us after all" and them sebastian and ciel get shocked and ciel wonders if he is refering to ciel or someone else?? Ciels lookalike also the nightmare ciel had in chp 108 of his twin confirms that undertaker is by the "real earl" side and he seems to be sick and given a medicine which might have to do with the blood transfusion experiments, if you look at the attacker physique and face structure it could be undertake. Ciel's twin might be the one Bravat refered to as "the star" that they are serving,, and ciels doubting sebastian might be because ciel thinks that the person in the photo should have been dead already (killed by sebastian?) but he is back now and the "who stole the candy" is a message to ciel from this person letting him know that he is well and back.
