I'm not agree with that. The sentence on the card is "Gigantic brother of the King of Ireland." (in french, "frère gigantesque"). For me it means that Morholt is a giant and not the king. Remember in HP5, when Hagrid introduces Grawp, he says first that the giant is his brother, and not half brother. It's well known that Morgan and Arthur are half in the arthurian legend. For Morholt and Gormond (the king in Tristan and Iseult), they don't seem to be linked in the real story and it's just a way to introduce him and that doesn't mean that the king is a giant. Giants are not known for their brain, I cannot trust that Rowling could choose to insult Irish like, saying that they are under the control of a giant. --   Famini    talk    contribs   19:14, October 28, 2011 (UTC)

Well (as I've just added to the page), in the real-world legends, Morholt is the brother of the Queen of Ireland, which would make this character his step-brother. We can't assume that the same holds true for Harry Potter canon, though, so we are forced to assume what the text implies: that they are full brothers. -- 1337star (talk) 19:19, October 28, 2011 (UTC)
It's not implied at all. "Gigantic brother" doesn't mean "The two are giants", it only says that one of them is giant. Hagrid in HP5: “See — he’s my brother!”, in you have only a few lines to introduce these two characters, you won't tell that they have the same mother necessarily, you could use a sentence more literary and say that Grawp is Hagrid's gigantic brother. It's the same here. Too much interpretation for a few words to introduce three characters... --   Famini    talk    contribs   19:31, October 28, 2011 (UTC)
Quite the opposite. Since the Famous Giant Card merely says "Gigantic brother...", it's speculation to assume that they are step- or half-brothers. And if they are brothers, Morholt's brother must be a giant, Q.E.D. -- 1337star (talk) 19:56, October 28, 2011 (UTC)
I'm not agree at all. It's higher speculation to add a status like giant and it's better to say it's possible that he could be one but he could not be one too because we don't know with these words if they have the two same parents. We could know it if the card says "brother of the gigantic king of Ireland". It's not written, so we don't know and it's a speculation to say in the page that it's perfectly implied. It's my last word. --   Famini    talk    contribs   20:04, October 28, 2011 (UTC)
