The Witcher "We wait." (Patreon)

The people who hired Geralt to get rid of whoever had a hold of Jaskier want him to press on with the hunt but he's not going anywhere until someone he trusts arrives to stay with Jaskier.

Might also be to get Jaskier to stay put because his concern for Geralts safety after what he endured might make him suck up his fear and try to help.
