First strip: d'awww. genuine love.
Second strip: see, this is what I mean when the dialogue bubbles aren't clear enough in which chronological way you should read them. In the last panel, we want to read Lillian's dialogue first, when it should be the other way around. Which kinda dampers on the punchline (that Roomie doesn't have anything on her mind, or at least that's what Lillian interprets her silence as, and then Lillian commenting on it).
And in the third panel, when Lillian sits down next to Roomie: I've always found that hard to draw. Someone sitting down. Especially when the panel cuts most of their body and you have to make their action obvious just with their upper body part. Lillian's way of sitting down doesn't look very natural to me here.
I should just take the time to observe and take references of people sitting down in real life and do some quick study sketches of it, and I'm pretty sure that would resolve (most of) the issue!
