I was watching Yesterday's Enterprise and I noticed something funny. At the end of the episode when Guinan and Geordi are sitting down and Guinan asks Geordi to tell her about Tasha Yar...it appears that Geordi is wearing the same uniform from the alternate timeline. Look at the end of his sleeves and his collar. Was that an intentional move, or just a blooper?? Sadly, I'm not able to post a screen shot of it, but be that as it may, I thought it was interesting.
