I had actually heard that giving her her contract causes her to just get pissed at you and do nothing. I'm not clear on what the strange conditionals there are, as I simply didn't find the contract (even though I swear I found everything and then some in the House of Hope) and am working entirely on second-hand experiences.

Still feels incredibly lackluster, tbh. Tying it to a companion (side?)quest via Karlach, or at least letting Mol half admit to you what happened and prompting a quest log entry or... something, could have made it feel far more significant and meaningful.
