(CNN)A 5th suspect. A 4-4 tie. And 2 pieces of debris. It's Thursday, and here are the 5 things you need to know to Get Up to Speed and Out the Door:


The race is on: Authorities now think there was a second man involved in the bombing at the Brussels train station. That brings the total number of men who carried out the airport-and-subway attacks to five. We know three died in the airport blast. We've seen the image of one suspect who may be on the run. And now, there's this guy, seen in surveillance holding a large bag. It all points to a much bigger terror network than suspected. And cops are playing catch-up, hoping there isn't another attack before they figure things out.

    Flushing your tax dollars down the toilet: Didn't we just go through this in South Dakota? Well, it's North Carolina's turn now. The state wants to require transgendered people to use restrooms that match their birth sex. The South Dakota governor vetoed his state's bill. The NC governor just signed it. State lawmakers felt so strong about this issue that they convened a special session, reportedly at a cost of $42,000.

    Four on four: This, ladies and gentleman, is why the Supreme Court needs nine justices. The court heard arguments yesterday on the latest challenge to Obamacare: whether the government can require employers to provide free contraception coverage to female workers. Religious groups say this violates their belief -- even though they can opt out just by filling out some forms. Well, the Supremes appear evenly divided on this one; a 4-4 tie. Paging Merrick Garland, or really, anyone.

    Dump Trump: In today's edition, we got Wisconsin Gov. Scott Walker saying The Ted is the "only one" who can beat The Donald. We got Jeb! throwing his support behind Cruz. And Mitt Romney's got jokes: "Donald Trump has had several foreign wives. It turns out that there really are jobs Americans won't do." The GOP is doing the Dems' job for them, but Hillz is getting in her shots too. Trump winning "would be like Christmas for the Kremlin," she said. Ouch.

    Mysteries of the deep: It's taken a couple of years, but the Indian Ocean is finally giving up its MH370 secrets. Two pieces of debris found in Mozambique last month are "highly likely" to be from the wreckage of the missing Malaysia Airlines flight, officials said today. The paint and other markings match the airline. The parts are consistent with the only missing 777. It's not hard to connect the dots. But are we any closer to finding the main wreckage? No one knows.
