That day, Casper was going out with Adam. It was the day before he would be going to the mission with the Sgails. Some preparations were still being done for the Seasonal Meeting of Jarls, so he got some free time to do what he wanted.
In the end, he tagged along with Adam, since the last was going to the Fourth Lab to get some materials and discuss some things with other scientists from there.
Casper was always curious to know how things worked in the other laboratories. He learned in a hard way what happened inside the Third, but he still had the Second and the Fourth to go, and now that he got the opportunity to do so, he surely would take advantage of it.
