I think her introduction was pretty fine, nothing odd about it at all.

The problem is that many people want to get through dialogues as fast as possible instead of "digging" into them (just like me). And the consequences of it are presented with Yen, for example. You can ask her about many things, and the more you ask her the more you know. For example during her first conversation with Geralt about Ciri's whereabouts or after the Last Wish quest (nice conversation about The Wild Hunt and amnesia)
