Matt who was taught to be suspicious of everything, began running over the events of the day in the short drive back to the A.R.C. He didn't believe for one second that Patrick was dead. Danny only said he ran through an anomaly, he never said he found the body did he? With this anomaly jumper on the loose, he had to be certain who he could trust and who he couldn't… Matt didn't have the previous friendship with Danny, so he was able to see more clearly around this guy. The close friendship the others shared with him clouded their ability to see anything other than the Danny they once knew. A lot could change through time, a person could change, for better or for worse. Most likely the latter with the experiences of the unknown pasts.
Emily was willing to forgive Patrick for what he did to her, he decided he should try his best to make up for how he talked to Danny earlier. Despite his theories about Patrick, he had no evidence, so the best thing to do was to continue as the others are, in a joyful mood from the reunion, but keep one eye open just in case something strange does happen.
Whilst on the thought line of the day's events, he also clicked back to when Danny said "It took you long enough to get here". What had he meant? They got there as as soon as they could. There was no delay in setting off? He would have to get Jess to check it out. Or get Connor to take a look at the ADD, it must be playing up, maybe a new update had a few glitches?
