Her 'Uncle' Jack had taken her up to Diagon for a day of shopping for christmas and school things early into their holidays, because he preferred the shops there to the ones in Mexico city. American shops were out of the question, because of their nationality, best not to be in the USA for them, they just wanted to shop without being harrassed. Jack, being Texan, wouldn't have a problem, but to protect Allegra he had decided that England would be all around the better choice.
And so the sixteen year old Hufflepuff was now entering the Leaky, one of Jacks favorite places and he and Armando visited on special occasions. Because of the seven hour time difference both were quite tired, having gotten up and left at four AM their time to be in England at 11 English time. Now it was one in the afternoon and Jack had sent her ahead to get her lunch whilst he picked up some more things.
It was packed, as it often was, but there was a large table still mostly free, so Allegra walked up to the pretty girl sitting there and smiled, her Mexican accent putting a pleasant lilt in her words,
"Do you mind if I sit here? I'm Allegra."
