1 Dwalin: It's wurse than we thocht. There're signs o' a stroogle. {translation: It's worse than we thought. There are signs of a struggle.}
2 Kyros: It's worse than that. If Lambert's been kidnapped or killed in his sleep, any of us could be next.
3 Alvissa: We have to find him. And the culprit. Or else we'll never find the Ruby of Dwarven Might and collect the reward for our quest.
4 Mordekai: Oh my. That's even worse!

I wanted the ranger in the party to detect signs of a struggle between Lambert and his mysterious abductor.

Until I realised there is no ranger in the party. So Dwalin had to stand in for one and display some actual adventuring skills.
