Uhm, well .. it's pretty surprising that Lois warms up to Clark that fast, considering the situation and its pressure
But hey, I won't complain if I get some cute scenes faster this way!
What I noticed too is the fact that both Lois and Clark asked about Tempus, this strange guy who appeared with Lois' diary and sent them into the future while they've not mentioned the Peacekeepers one single time. I dunno, but it's not surprising that they got THIS reaction! Anyways, if I met two time travellers, one good and one bad, Lois would probably search out for the bad one (so the story is more fun)
