CONFIRMED - Justin's Injury HAS to be Fake!

After my team of investigators went back to the online video: http://abc.go.com/watch/the-bachelorette/SH5556990/VD5570292/week-3-part-1?cid=fullepisodeaccess  of last week's episode, I have come to the following conclusion:

Justin's injury MUST be fake.  When Justin is hiking to Ali's house on crutches, it is clearly his LEFT foot that has a protective boot on, and which he does not walk with.  This indicates that it is his left foot that is injured.  We then see Ali being videotaped at her house. She is discussing her upcoming date with Hunter and why she chose him.  For a second, we see a clip of Justin right before he approaches Ali (it's in the last clip of Episode 3, Part I).  This time, however, his RIGHT foot is in the boot, with his sneaker on his left foot.  Unless ABC is playing mirror camera tricks with us, Justin has SWITCHED his injured foot. I repeat: JUSTIN has SWITCHED his injured foot from left to right. 

A moment later, in the next shot, Justin's injured foot is back tp being his his LEFT foot.  This is at the point where Ali sees him.  This shocking mistake can only mean one of the following:

1. Justin's injury is fake and ABC knows about it.  How could they not have captured him taking off his foot boot cast thing and changing it to the opposite foot?  Perhaps they missed it or didn't realize what he was doing when he switched the cast to the wrong foot.

2.  The clip we see of Justin with this foot boot on the "wrong" foot is really being taped in a mirror somehow, and therefore it is really on the same foot the whole time.

3.  Justin's foot cast switcheroo went unnoticed by anybody somehow, even Justin - he wasn't smart enough to keep the hoax up the entire time. This would mean that he stopped to rest at some point and "air out" his foot.  We didn't see him rest.  But a mile's hike on crutches on a highway may have required some rest.  Even a 5 minute break would be enough for him to have taken his cast off and then, "Oops!" put it back on the wrong foot.

1 and 3 above are most likely.  Gotcha, Justin!  What do you all think?
