Okay I was just reading on wikipedia and it really got me thinking.
now that I think about it those vortigaunts from the start of HL1 I think they are somehow related to the ones at the start of HL2: E1. What do you guys think
However, their influence on Freeman may precede the G-Man's. This is not the first time a cultish group of vortigaunts has been associated with a character's rescue from an explosive situation. One of the "flashes" or teleportations Gordon undergoes during the original Black Mesa incident resulted in him finding himself within a circle of vortigaunts who were strangely unaggressive with regards to his presence. Originally, players were likely to believe that Freeman had simply intruded randomly on a gathering of surprised, hostile aliens--but in light of Episode One, it seems possible these vortigaunts were one and the same, and they may have had a significant role in Gordon's survival of the test chamber catastrophe. Of course, as per Half-Life's storytelling conventions, other characters assumed this feat--like many others of Gordon's--could be attributed to his hazard suit.
