I'm actually leaning toward Loki, now, though - I mean, is latching onto another suggestion supposed to make you less suspicious because you told us it's usually suspicious? My brain hurts.
Ah, I can now see what you meant. That was not my way of thinking at all. My reasoning was simply that Linds latched onto the suggestion to kill Gareth.
Maybe I should elaborate my trail of thought a bit more.
If a killer goes the "be the first to suggest a lynching" route, it makes them instantly suspicious to others. Case in point:
The first person to suggest a lynch is almost undoubtedly a killer.
Therefore, it would be prudent for them to wait till some lynch-zealous villager X suggests someone Y to lynch and then say that "yeah, now that you mention it, Y is pretty suspicious. Let's lynch them." All the better if they have a believable motive to lynch Y. It matters little to them
who gets lynched, so Y is as good to them as anybody else, and it gives them plausible deniability when Y turns out to be innocent ("look, I wasn't even the first to suggest lynching Y! X suggested it! Let's lynch them!"). That also allows a plausible way to lynch
two innocents.
...Unless, of course, the killer(s) already predicted that we would come up with that theory and double-bluffed. That should then make de_la_Nae or J suspicious.
J's suggestion is, in fact, quite a conundrum to me. It doesn't seem to be based on anything except paranoia. Unless, of course, J somehow knows more than we do, by way of having abilities above ours and knows for a fact that Linds is going to kill us; then they might have just bought themselves a life insurance for a few nights, because it would be very suspicious if J died the day after they accuse Linds; we would then likely encounter some evidence that they were speaking the truth when accusing Linds, leading us to lynch Linds on the spot.
TL;DR: I suspect everybody.
