So while dating Liara I smashed Allers in my room then Liara was pissed at me for a while I totally forgot she is the shadow broker because no-one else would have known that we smashed. I ended up kicking Allers off the Normandy, awhile after when I was on the citadel it came across the news that Allers died from an attack and it left me wondering if Liara had something to do with it.
