Well with his background a "We need to talk about Maeglin" situation was perhaps always going to be a possibility. Galadriel was said to be tallest of elven womem estimated at 6"4 and Celeborn of like height. Maybe not exceptional for an elf man though the Teleri were meant to be generally less tall than the Noldo..though the most prominent Thingol, Círdan, Celeborn are all described as tall. Who knows, maybe they are being sarcastic (cf Celeborn the Wise
), maybe it is a euphemism
