I had a thought about Lalli's behaviour on page 290 (actually, it more-or-less relates to how Lalli behaves all the time) that people thought made sense, so I'll post it here:
Someone said Lalli hiding under the blanket and staring at Reynir on that page was so catlike as to be unbelievable. It might look like it's a tiny bit strange, but Lalli is not just a poorly socialized individual, he also grew up around cats, who probably were his "colleagues" in a deeper sense than other night scouts were. As a night scout, you are given a chunk of land to patrol, your routes are not likely to overlap with those of other scouts, but cats - those go where they please, and might well keep scouts company. Presumably, there were cats around even when Lalli was younger, given how much people rely on them in that world (and given Lalli is clearly an introvert, he'd prefer their company to most people's). Now, if you spend a lot of time with an animal of another species, behaviour rubs off...I've spent more time interacting with cats than I did with humans between ages 3 and 10, and I do have a lot of cat-like moments even now as an adult. Actually, thinking about this made me realise that I stretch waaay too much in not-terribly-appropriate moments (like conferences, teehee, to which I go a lot, because I am a grad student). I like curling up (my neck doesn't, but somehow I wake up to find myself in cat-posture every day, go figure), look at unfamiliar objects the way Lalli looked at Reynir, and my body language is kind of cat-like in general, I've been told. I don't really think it is, actually, but people keep saying "oh, you're catlike". Sure, whatever.
So, on that page 290, it looks like it still is the day following the night Lalli spent scouting (i.e. day 2 of the trip). Lalli is tired (he's been kinda tired in a lot of panels after that troll hunt). Lalli wants to sleep. It's light outside, so he'll sleep with the bedsheets over his head. But he's also curious about the new dude, so he'll take his peak. To me, it looks so normal for someone poorly socialised who grew up around cats. If someone wakes me up, and I am in a good mood, but don't really want out of bed, I'd probably hide under the sheets and watch them vengefully for a few minutes. Because having little silly rituals like that feels pretty satisfying somehow.
