Vladimir's Return???

Okay so we all know our wonderful freind Vladimir from Metro 2033 and Last Light.I have a sneaking suspicion that he MIGHT make a return in Exodus.Watching the trailer closely, and with the speed set to .25, just before the camera changes as Artyom gets onto the train you can see someone standing inside the train behind Anna.Now of course this could be anyone, this can be someone we know or some random ass Ranger whos going to die at the next stop but this is just my theory.I believe this character might be Vladimir and heres my reasons why:Looking at this picture, i have outlined the character. He isnt wearing anything that sybolises him as anyone else like Khan with his hippie bandana. Instead he is wearing the normal Ranger uniform and some light body armour.As stated on the wiki of Last Light and 2033, what we know about this character isWhat we see here is someone using light body armour or even just a chest rig. It says that Vladimir is not a warrior like the rest of the rangers and is linked to why he doesnt wear armour.Appearance wise, we know that from Last Light, Vladimir has a clean shaven head and wears glasses. In the picture above, we see a man with very very short hair. Bare in mind, this is based in 2036 which is 2 years after the events of Last Light. Also, from what i can see from the image the man appears to be wearing something on his face, most likely a pair of glasses (I dont know if thats just me but it looks like it).Moving on, it is stated that Vlad is a technician, over 40 years old and has had pre war military training. He knows of pre war technology which is why i believe he may return. The Aurora (the train for those who dont know) is very very pre war and will need someone with the knowledge of such pre war technology to help run and maintain her. Vlad seems the perfect man for the job.I dont know if its just me, but i became really fond of the small characters you meet in the armouries such as Vladimir and Pavel and so i personally would love to see this small character make a big comeback.Let me know your thoughts on my theory and your own ideas on who this character might be.
